I realize it's impossible fit someone or nail their ideal bike size over the internet and that's not really what I'm looking for.
I'm seeking a second opinion after a confusing and somewhat unsettling fitting experience I just had with a local well known and respected bike shop here in New England.
My dilemma comes from a visit to a local shop to buy a Cervelo P2. I went in thinking I would fit nicely on a 55cm, 700c frame, but came away told I would be much better off on a 52cm frame. I'm concerned that either I don't have any clue about my position and bike fit on a tri bike (which could definitely be true), or that the person sizing the bike to my needs didn't understand tri-bike geometry and/or how to position someone on a tri-bike. Or we're both out to lunch.
Here's some info:
* I'm 6'1", 180lbs, 88cm inseam and normally proportioned body. I have pretty decent hamstring flexibly.
* I come from primarily a road racing background with the last few years racing mt bikes and cross racing. (20years of riding experience)
* Started racing Duathlons last year and this year wanted a bike specific for Du's.
* Currently ride a 59cm ti road bike (57.5tt with 73deg seat and head tube)
I test rode a 55cm Cervelo P2, liked how it felt, shop fit me using a Serotta size cycle. He started the fit using a 78deg seat tube, but for some reason abandoned it and went to a 75deg set-up. (I think he didn't like where the plum line from knee to the pedal was falling) After tweaking and adjusting he said that I would need such a small stem (70mm or so) and that my weight distribution would be heavy on the rear and unstable/light on the front. They recommended I would be much better on a 52cm. This seems really small to me especially when you consider, I'm 6'1" and they're recommending the smallest 700c frame size Cervelo makes for the P2k. What kind of people are using 55's, 58's or 61's?????? They are ordering a 52 for me based on their numbers. I want to support this local shop as they the only Cervelo dealer in the area but this just felt all wrong to me and my gut tells me something's not right.
Sorry to ramble on, but I'm really confused on what to do.
