How to enjoy riding a 50lb bike...

Last week I took a fifty pound bicycle for a couple of rides and enjoyed every minute. No, I'm not talking about some mega-travel downhill rig: I'm far too scared to take one of those anywhere near what they are capable of; nor am I about to be certified insane, as far as I am aware. The bike in question was a Dutch shopping bike, with a sit-up-and-beg riding position, and built with a construction philosophy that the designer of the Panzerkampfwagen IV would have approved of. Ladies and gentlemen, I give you the Montego Elan.

The Elan belongs to my mother and the background scenery is Murcia in Spain, where my parents reside. She very kindly allowed me to let it loose on the hilly terrain around their house and I was able to sustain an average of 14.2mph, dressed in my everyday clothes.  The secret, as the eagle-eyed among you will have picked up on, is the electric motor in the rear hub, supplied with power from the battery pack above the luggage rack.

I haven't ridden a hybrid before and it really is something every cyclist should try. The motor assists the rider on the 'Pedelec' principle, kicking in when the rider exerts a given level of effort, the threshold being determined by a controller on the handlebars. You have to keep pedalling, but the motor helps when the going gets tough. While the motor is no powerhouse and you have to make full use of the seven gears, it's pretty effective and would give you an hour and a half or so of assistance on the 'full' setting. The riding position is awful, the saddle far too wide and the tyres squeal at the slightest hint of a corner, but somehow the absurdity of it all makes it hilarious.

I gather the Chinese have gone in for these bikes in a big way and see no reason why they should not become more popular in other countries, particularly for the non-enthusiast cyclist, who wants to commute, ride to the shops or keep up with the kids at the weekend, for example. I can even see interesting  applications for the keen cyclist, particularly using a more powerful motor and lithium-ion batteries.

For someone who wants to commute a longer distance, electrical assistance could reduce the time  of the journey to something that can be fitted in with other commitments.  It would have the advantages of low cost,  and could enable getting to work without becoming hot and sweaty. The motor cold be used in conjunction with  a single-speed,  keeping the bike simple, allowing a decent gear for speed on the flat, with assistance for the hills, or with a tandem, which can be a bit of a slog when the road goes up.

Of course no self-respecting sporty cyclist would touch one, let alone a racer. Or would they...?

Following on from my previous blog, the weight loss monitoring is now going to commence in the New Year, fortified with a resolution. Blame this on my parents' hospitality, electrically-assisted cycling and the impending Christmas festivities. Poor excuse, I know!

Weight Weenie


On the face of it, I've had a good cycling year. I've put in a reasonable number of miles, according to Strava:
YEAR-TO-DATE
Distance 2,793.0mi
Time 208hr 59m
Elev Gain 61,378ft
Rides 174
I've participated in a few XC races, cycled off road in Wales, the South Downs and the Alps, so some wonderful contrasts to flat ol’ East Anglia and I've built up a decent stable of bikes to satisfy my inner techno geek. The thing is though, I've found it rather hard work and this is manifest in a number of ways:
  • My average speed is nothing to write home about (15-16 mph average for solo road rides).
  • I struggle on steep climbs with the 34x36 bottom gear on my Whyte 146.
  • I keep getting dropped by my younger brother, who hasn't done as much cycling as me. This is the worst thing!
Now I accept that being in my mid-fifties, I should expect everything to start going downhill, but I know that this needn't be the case as many ‘grand-vet’ – 50 year-old+ competitors in XC races post times close to those in the younger age categories, so it’s not necessarily an issue of age. No, my theory is that the key element is bike weight and I am determined to reduce the heft of all my bikes significantly. There are two approaches to making a difference in this area.
The first method is to invest in lightweight componentry. Thing is, my bikes are pretty light anyway and I know that sinking a small fortune into exotic parts will make no significant difference. No the only way forward is the second option: to reduce the weight of the largest single component, the rider (me) and this is clearly an overweight component. At 5’8” tall, and weighing 83.7Kg, there is scope for some significant weight trimming and I am anticipating three benefits:
  1. Improved climbing and acceleration. I'm hoping to be able to push that 1x10 setup on the Whyte with ease, improve my race placings and stop being dropped by younger brother (important, that one)
  2. Saving money – no need for silly equipment purchases (we’ll see…)
  3. Looking better. This is a difficult one, because weight gain is an insidious thing. Mentally, I think of myself looking pretty much the same as I did as a teenager, but the physical reality was brought home to me by recent photo (when I clearly wasn't ‘sucking it in’) posted on Facebook by one of my riding buddies, Brendan (yeah, cheers old boy!). I am including it, together with the associated words of reassurance, with great sense of personal shame, to illustrate the extent of the problem. Ouch!

Julian appears to have stuffed his bladder under his rain jacket !!
 — with Julian Greaves and Gawain Edwards at Coed y Brenin.

Well, that’s got that out of the way. Harsh but fair, I suppose (pause to wipe tear). Anyhoo, the plan is to lose 10kg, which will put me firmly in my ‘normal’ BMI zone, before the next ‘Mud, Sweat & Gears’ race in the Spring and we’ll see if that makes a difference. The weight loss programme is going to be a simple one, namely to eat less and exercise more and in order to achieve this I am following these simple principles:
  • Three meals per day, with nothing in between, unless on a long ride.
  • Drinking sensibly. Booze on only two nights of the week.
  • At least six hours of cycling per week.
There. Simple. Just so that I don’t stray from the plan, I will be publishing my progress on a weekly basis, together with any deviations.
Here goes!

My weight: 83.7kg. 10.7kg to go. My weight goal is 73kg http://withings.com

My Winter Bike

Well, it’s that time of the year again. North East Essex has pretty much the lowest UK rainfall, but in the winter months, the roads rarely seem to fully dry out. A great feature of this part of the world is the large network of minor roads that link farms and villages, allowing cyclists to keep off the main roads and away from traffic. Unfortunately, because they have a great deal of agricultural use, they are often covered in mud from tractors and soil washing off fields when it rains. These roads aren't all that well maintained and have a lot of potholes, cracks and fissures, which may be covered by mud or puddles and can be difficult to spot, particularly at night. Consequently, it’s well worth having mudguards and a set of strong wheels, and a second bike built to accommodate them will mean that your lightweight pride and joy will have to contend with nothing more challenging than the odd spot of ultraviolet light.

The Roberts Twins

My winter (well pretty much three seasons of the year) bike is the blue one in the photo, one of a pair of frames ordered at the same time (c.1993) by my brother and I from Roberts Cycles in Croydon. We both wanted straightforward lugged road frames, made from Columbus SL tubing, an alternative to Reynolds 531 at the time. According to Chas Roberts, we did not really need custom frames because we have arms and legs reasonably in proportion to our bodies and an ‘off the peg’ frame would have served perfectly well. Custom building does have other advantages though, giving more choice over any desirable features, in my case a bike with clearance for mudguards.

The frame was designed so that there would be sufficient mudguard clearance using short-reach side-pull calipers at the full extent of their reach. At the time, Shimano made a long-reach side-pull (from the 105 groupset), which would have given more clearance, especially with larger-diameter tyres, but I was keen to use all Campagnolo kit, so short-reach it had to be. With the benefit of hindsight, I would have gone for the 105s as accommodating 25mm tyres and rattle-free guards has always been a problem. I'm not a big fan of cantilevers and it’s only recently that Campagnolo have made a set with the correct leverage ratios to match Ergopower levers.

One key essential in a good winter bike is a strong pair of wheels. I had a set built with Campagnolo Record hubs, 36 DT stainless double-butted spokes and Mavic Open Pro rims. These wheels have inadvertently been crashed into all the road defects mentioned above, yet remain completely true and need relatively little maintenance, just requiring a splurge of grease through the injection ports each autumn. The design is a big improvement over their relatively heavy steel-axled predecessor, using strong yet light wide diameter aluminium axles and the cup and cone setup is very easy to adjust. I think Campagnolo have stopped producing them in polished alloy, which is a pity. Tyres are 25mm Continental GP 4000S. I’m becoming a big fan of wide-diameter lightweight tyres as they manage to combine comfort and grip, especially in the wet, and don’t seem to produce significantly more rolling drag.

I’ve settled on Salmon mudguards, because they are the only ones I have been able to find that don’t run underneath the callipers and consequently give more clearance. The front guard stops at the brake caliper and the rear has a linking bridge that goes over the rear brake. It looks a bit clunky, but it does work. The guards are narrow strips of polished alloy and despite not wrapping round the tyre, keep water from splashing up my back and up into my face. My feet do catch some spray from the sides, but that’s what overshoes are for after all!

I now avoid ice!
The Roberts is my longest-lived bike and is still in regular use, although because of my equipment OCD, only the steel of the frame has survived without change. The bike is significantly heavier than my Ti Burls (22lb vs 15 lb) and isn’t as stiff, yet the weight is only apparent when you step off one and get onto the other: once rolling for a few minutes, it is still all you could ever really want in a road bike. The bike will take me through the winter very nicely, although I do make a point of washing it after a ride, particularly if the roads have been salted. I do draw the line, however at going out once the temperature drops below zero. Two winters back, I came down on a patch of ice caused by water running off a field and freezing. The fall was instant and unavoidable, given the camber of the road, and resulted in a rather bruised hip and a nasty bang on the head (saved by my helmet).

If I was starting building again from scratch, I would think long and hard about a Ti frame (light and rust-free), hydraulic disc brakes (they’ll work in the wet, will be maintenance-free and allow bags of mudguard clearance); I’d be tempted by even wider tyres – 27mm Dugasts would be nice – and the rather lovely hammer-finished Honjo mudguards. To top it off, belt-drive and a geared hub (e.g. Alfine, Rohloff) would make the bike pretty much maintenance-free. Hmm, I’ve got to say I’m really tempted!

Five Go Camping: Dusk To Dawn 2012

'Dusk to Dawn' is a twelve-hour mountain bike race taking place each October in Thetford Forest, starting at eight in the evening and running through to the following morning. There are a number of entry types, from solo to four-rider teams. Given that I haven't the faintest chance of sustaining any sort of race pace, or even non-race pace for twelve hours (two usually being my maximum), I entered in a group of four, VC Les Poubelles, comprising Gawain (the organiser), Brendan (the triathlete) and Antony (my brother).

D2D 2011 

The misery of 2011
It wasn't our first foray into this race, the 2011 event providing a baptism of fire, well, more one of water. On Saturday, a band of rain moved over Thetford in the late afternoon and stayed in place resolutely, only increasing in intensity, until it was time to pack up the following morning. Thetford is normally sandy and well-drained, but on this occasion, became a complete and utter mud bath  On my first lap, I was even fishtailing on the fireroads due to lack of traction and getting any grip on the singletrack sections was only possible by riding up the sides of the puddles in search of any patches of grass. My second lap was a complete disaster, my lights battery dying halfway round the course. I guess that's what happens when you don't charge them between laps! I can't convey the misery of having to push a bike through a sea of mud in zero visibility and it was only with the first glimmers of dawn, at around 7 am, that I could remount and continue riding. That lap took over two hours, twice that of my previous one and guaranteed a low placing; the team only managing seven laps completed.

We just weren't prepared for the conditions and I spent most of the night wet and miserable, desperately trying to absorb some of the meagre warmth of a camping gas light. The conditions ware so muddy, that in addition to needing to jet-wash the bikes after our laps, we had to jet-wash our legs as well! We vowed to return, prepared for all eventualities, in 2012.

Glamping

Camp butler (Not a reference to a flamboyant demeanour)
A key to success in this type of event is a good base. With each rider doing one lap of around one hour, there are three hours between laps to maintain fitness, well-being and enthusiasm  Nothing was left to chance this year. We had a large tent, an 'event awning', generator, electric lights and battery charger, jet-washer and a gas stove for food and coffee. Our rabbit-in-the hat this year however, was our fifth team member, Andy, who for some reason had volunteered to be a sort of 'camp butler', that is to say, chef, bike cleaner and general dogsbody. What a star! I had a good feeling as we set up camp in the late afternoon sun (no rain in prospect this year) and indeed, indulged in the odd spot of relaxation. It was promising to be an enjoyable event.
Contrast to 2011


















The race

While still muddy in places, due to rain the day before, the course was a joy to ride, unlike 2011. The course can be seen in my Strava plot of lap 2, above, and was  a nice mix of fast fire road, wooded singletrack and the odd bomb-hole. For Thetford, which has a lot of stutter-bumps on the singletrack, it flowed pretty well and we put in laps at around the hour apiece. The organisers even put on nice little touches, like playing classical music over speakers and hanging little fairy lights in the trees with about a mile to go which lessened the pain a little at that point.

The race etiquette this year was excellent, with everyone calling which side they were going to pass on, no abuse and just general good manners all round, which improves the feel-good factor. Change-overs were amusing: some riders seem to like clanging the anchors on, sliding, speedway-stylee, to a halt millimetres from the barrier, while bellowing the name of the next rider at the top of their voice. It wasn't difficult to spot your team-mate in the transition area and hand-over the team wristband without the drama, but it takes all sorts I suppose. Most of them did go a lot faster than us, to be fair.

My lap times were 01:01:47, 01:03:23 and 01:05:16, increasing progressively as expected. They felt very different though. Lap one was painful, although it felt fairly fast as I managed to overtake quite a few people. Lap 2 felt fantastic and I thought at the time that was going to be faster than the first. Maybe it was because the course was more familiar, but it did seem to flow better. Lap 3, in contrast felt awful; I just could not seem to get any speed up and was continually being passed by faster riders. I was convinced that it would be at least 20 minutes slower than the last. Funny how feel doesn't reflect the actual speed. I'm always amused at how I handle the bumps on successive laps as a result of exhaustion:- Lap 1: flowing over them in a supple manner, legs complimenting the suspension; Lap 2: letting the suspension do all the work; Lap 3: crashing into everything, while just about managing to hold on!

End of final lap
Overall, our performance was much better than last year, with 11 laps covered in 11:59:22. Yes, we could have done another lap which might have pushed up our position a couple of places above our overall 36th in the four-rider category. Mind you, that was SEVEN laps down on the winning team. The fast guys really are impressively fast.

So, was the experience better, given the improved logistics? Yes, certainly, yet this year's weather problem was the cold. We had a cloudless sky all night and the temperature dropped to around freezing by morning. I tried to get some sleep between laps 2 and 3 and despite wearing my riding gear, my jeans and fleece, jacket, woolly hat and wrapping up in a sleeping bag, inside a car, I was frozen. By morning, fog had rolled in, adding to the feeling of cold and keeping the course slippery until the end. We could have done with a wood-burning stove in the tent, but I think that would would have been a step too far. It would have been nice to have had some source of warmth for getting changed and sitting around between laps, though.

Cheerful younger brother enjoying fog
The 'butler' idea was a mixed success. Yes, he did make the odd cup of coffee and clean a couple of bikes (mainly for other teams), but then he locked himself up in his Lexus, heater on, for most of the night, emerging only for breakfast. You just can't get the staff! Still he did make some decent bacon and sausage sandwiches which redeemed him, I guess...

Overall, I'd have to say we had a pretty good time, but we don't think we'll do it again. There's that awful doldrums period in the early morning that is just plain miserable, if it's cold and/or wet and we're just getting too old for all that. We might have a go at a daytime enduro or perhaps a midday to midnight race next year, but we'll have to see.

Standout kit

Lumicycle lights

The LED lights are fantastic. Lots of light and good battery life  With a bar-mounted and helmet-mounted light combination, operating from the same battery, visibility was excellent. Having a generator to allow between-lap charging meant that there was no anxiety over battery life this year.

Bontrager Mud-X tyres

While there was still a degree of slithering around, these tyres grip brilliantly, don't clog and run tubeless with Stan's. I wouldn't race in mud now without them.

Kestrel Carbon to Burls Titanium

I really must think things through before upgrading. What started as a simple component swap escalated into a major project last year. Despite having a perfectly satisfactory fin de siècle Kestrel 200 EMS, I managed to track down a titanium-steerer EMS fork to replace the steel steerer version purchased with the frame and one I had inadvertently cut down rather too far for comfort. I had always hankered after the titanium-steerer fork and used the refit as an excuse to go 11-speed at the same time, transferring the Campagnolo Record 10-speed kit to my steel Audax/commuter bike. I felt that the alloy Cinelli 64 bars could do with an upgrade to carbon, and  26mm Kestrel carbon bars were chosen to go with the existing Cinelli Grammo stem. I was happy with the result...briefly.
Sadly, when it arrived, the fork steerer turned out to be threaded, with the threads extending to below the lower clamping area of the stem. It went together well enough, and I'm pretty sure that the titanium would have been sufficiently strong, yet there was always the nagging doubt that the outcome of a breakage would involve an inadvertent face/scenery interface (nooo, not the face!) It wouldn't do and besides, the new bars had too much reach and the titanium spacers didn't match the stem!

Despite being state of the art in 1999, the Kestrel had become somewhat archaic, having a 1" steerer. Luckily, Columbus make a light, carbon-steerer 1" fork, the 'Minimal' but there are  no suitable 1" steerer stems available that would work with the 31.8mm diameter of my chosen shorter-reach carbon bars, the sexy Cinelli RAM. In the end, I managed to fit a Thomson X2 stem, using a cut-down Thomson Elite shim, together with some matching alloy spacers, giving a good cosmetic result.

I'm not sure whether it's the combination of carbon bars, stiff stem and carbon fork or whether it's the state of the roads after a cold winter and wet summer, but over the filled and unfilled potholes, fissures and many many stretches of rough chip-seal, characteristic of rural Essex, the bike gave a bone-jarring ride. I replaced the 22mm Continental tubs with Veloflex Roubaix 24mm, which brought an improvement, but really the ride was still as hard as hell and the whole thing just wasn't working: I found I was using my Roberts steel Audax bike in preference, most of the time. Time for a new frame...


Despite any shortcomings, I think the Kestrel was very elegant, as carbon frames go. I'm not a big fan of the current vogue for massive cross-sectioned head/crown and bottom-bracket areas characteristic of modern carbon frames, however and it got me thinking about steel again. When it comes down to it, a steel frame may weigh a couple of pounds more, but always gives a good ride and I much prefer a more traditional look. Who to buy from, though?

This is a rather long preamble into my decision to go for a Burls frame. Justin Burls is based in nearby Harwich, where he has built steel frames and has more recently diversified into titanium. I remember him starting making frames and being impressed by the high standard of workmanship of even his earliest ones, so I made enquiries. It turned out that he wasn't building steel at that point in time, but could provide a bespoke titanium one; the manufacturing being subcontracted to Russia, where the builders had the necessary expertise and experience in fabricating this light but difficult to weld material. It is generally accepted that titanium has a vibration-absorbing ride, it looks great, doesn't require painting and can be configured to taste.

We decided on a road frame, with geometry loosely based on my Audax bike, which I have always found to be very comfortable. I had recently met another rider with a Burls Ti frame and was very impressed by the look of it. He had opted for curved seat stays and fancy tube profiles, which while appealing to my inner bike geek, detracted from the more classic appearance I was after and I decided to go for straight stays and round tube profiles. Forum discussions abound with tales of the flexible nature of titanium and I was anxious to achieve comfort along with lateral stiffness so that there was no front derailleur rub when pushing out of the saddle. Justin recommended 32mm seat and top tubes, together with a 40mm downtube to achieve the desired characteristics. No 'compact' frame geometry either: I prefer a horizontal top tube. The frame is finished off with a curved Easton EC90SL fork which is light and has a nifty internally-threaded star-nut gizmo. Justin provides a CAD schematic to show the dimensions and geometry and even demonstrates that there will be no toe/wheel overlap - a nice touch.

So, does it work? Well, yes it does and titanium really does live up to the hype surrounding it. The frame definitely absorbs harsh road surface vibration, yet has that 'zingy' feel of high-end steel frames. The geometry gives it sharp, accurate steering, yet allows the bike to feel completely stable in long, fast corners. Happily, the frame has no front derailleur rub when out of the saddle, so works just as anticipated. According to my luggage scales, it weighs 15lb with pedals and bottle cages, so while a little heavier than the latest carbon frames, it's still pretty darned light. Any further weight saving is going to have to come from my waistline! Kit is:

  • Campagnolo Super Record 11-speed groupset (2011, with 2010 50/34 chainset).
  • 12-25 cassette
  • KMC X11SL chain
  • 1990's Shimano Dura-Ace SPD pedals
  • 1999 Campagnolo Nucleon wheels
  • Veloflex Roubaix 24mm tubulars
  • Thomson Masterpiece seatpost & seat tube clamp
  • Selle Italia SLR saddle
  • Chris King No-Thread headset
  • Thomson Elite X2 stem
  • Cinelli RAM bars
  • King Cage titanium bottle cages

Is that it, then? Well I'm not sure that the bars are the best design ever. They're very stiff and transmit vibration, routing the cables is a nightmare and they're, well, just too 'frou-frou'! I think the new Thomson road bar would work very well, but that will have to wait for a while. Apart from that, the bike is fantastic, a joy to ride and one I expect to keep for a long time.

I would recommend Burls highly: the frames are of very high quality and are priced very reasonably. A frame like this one will come in around the thousand pound mark, plus fork, which while not cheap, represents outstanding value compared to a lot of high end carbon frames, American titanium frames and indeed many custom steel frames.
