As well, they usually have more lax head tube angles; a race-type bike will have a 73-74 deg HTA, a comfort bike will have a 72-73 deg HTA. The comfort bike may have a more lax seat tube angle as well.Snopro440 said:usually have taller head tubes and shorter top tubes so the riding position is slightly more upright.
I can understand how the turning is compromised on a longer wheelbase biketjjm36m3 said:Pretty comfortable by eliminating small road buzzs, but sucks in tight turns and fast descents.
Well, here is my take. I have been riding for a year now and I have found that fitting is everything. I was currently riding a C'dale synapse 6 which had the rei fitting. "do you have aprox 2" in the crotch to top tube?" That bike was fine but I decided to upgrade. My choices were Felt z35, Scott cr1, and cervelo S1. I spend about 4 to 5 hours at the LBS that carried all 3. The first hour fitting one of the bikes to me. then, while I was putting 6 to 10 miles on it, they would set up the next one to the same measurements. I would come back, do a quick fit check and be off again. When It was all said and done, I chose the Cervelo S1 which is supposed to be more of an aggressive geo and posture. It rode just as smooth (IMO) as the other 2 or at least I couldn't tell the difference. And was as comfortable if not more than my unfitted synapse. I have been riding it one week and have put 100 miles on it and I feel fine after the ride. 48 miles yesterday and though tired as it was my longest ride ever, I didn't have to go home and lay on the couch. My point is, that I think if someone knows what they are doing in fitting you, then they should be able to make most any bike fit you. And I am not sold on entry level carbon bikes over top shelf alum. bikes.PTV said:Just how big a difference do these "plush" bikes make in terms of comfort ?
Really? That seems odd, considerin' that some full-on race bikes can barely accept 700x25 tires, much less anything truly 'fat'. :skep:thirdin77 said:Of course, some people who ride race bikes say this is all pointless. Their criticism is that you can put fat tires and a riser stem on an race bike and it's as comfortable.
No, you misunderstood. I said that I was able to get fitted to a race geometry bike and it was as comfortable if not more so that the synapse that was just top tube fitted. And I didn't spend 4 hours getting fitted, I spent for hours at the bike shop with the first hour getting fitted and the other time trying out the 3 different bikes.PTV said:Interesting - thanks...... Guess you got lucky with the Synapse - as from what you describe it fitted you as well as a frame you spent hours getting fitted on!
