If the choices are a bike that is comfortable and another that goes up hill like a scalded cat then the comfortable bike gets left behind. But the differences are not that pronounced. Probably not but my point was that any real competitor wants to win and given the choice of a comfortable bike and a bike that is, say 10 minutes faster up "Big Bad Mountain" my guess he will ride the faster bike. For a 1 hour long steep climb where wind resistance is negligible, to be 10 minutes faster, the weight of the fast bike + rider would need to be about 5/6ths the slow. That would mean somewhere in the vicinity of 10kg weight reduction. Is that why Froome threw his bike away last year in Le Tour and began to run, do you think? Well yes, a 10 minute faster bike is a bit of a stretch but the point is that you, or any other serious contestant, will take every advantage that they can and if a bike is faster for a certain race then I suggest that you will select it over a more comfortable bile. I knew what the point was. I suggest that when you spend 4-6 hours a day racing over mountains and such on public roads, comfort isn't ignored because at the end of the day a rider that feels a bit fresher by not having been beaten by his bicycle, is more likely to win - all else being equal. Comfort, to some extent at least, is an advantage. I think John B. is envisioning a TT or aero-bike where rider position is learned and totally uncomfortable for civilians. I've never found a properly fitted racing bike uncomfortable. I've never had a bike that "beat me to death" on ordinary roads when it was properly adjusted, although some of the early clincher tires were like riding on wagon wheels as compared to tubulars. Those days are gone, and I would bet that the best clinchers with latex tubes are pretty close to tubular comfort. -- Jay Beattie. Try comparing your Roubaix to an S-Works Venge. I'm not saying it's totally uncomfortable just that it's way overkill for anyone not racing and uncomfortable for someone that really needs more of a Roubaix type bike. |
