does bike size effect performance(5 posts)

I ride a 56cm frame I could ride a 57 or 58. I have about 3 to 4 inch stand over on a 56cm. I have long legs and a short torso, so I feel comfortable with the reach and the position of the bars. Seat post is a little high but doesn't seem to be a problem. A couple of guys in my group ride keeps telling me that I could use a larger frame. I feel fine and comfortable with the one I'm riding, but am I losing any performace from riding a smaller frame?

Which explains all the unsolicited emails I receive making size promises if you use their products.

With that said, if the frame you have fits and you feel good on it then why would you change. A larger bike would be heavier and theoretically would have a longer wheelbase that would make it less responsive to quick input by the rider.

Lot's of people would like to be riding with extra larges but if they don't fit, they don't fit.
No, but bigger bikes are more satisfying. nmdzrider

Probably, but not as much as fit doescory

This is purely from my personal experience, but based on that, nothing matters as much as fit. If you're comfortable on the bike, I wouldn't give it a thought.
One caveat, though--for about 20 years, I thought I was comfortable on a 62. When I bought my Atlantis, I used the Rivendell fit guide and it put me on a 65, which they didn't make at the time. I ordered a 64, and there was a pretty significant improvement in comfort over bikes I'd ridden for quite awhile and really liked. So I could ride longer, go harder and improve performance that way.

My stats are virtually identical to yours, including the the size bike I ride. When I have test-ridden larger bikes, the setup (ie, seat height, reach and drop) ends up being just about identical to the positioning on the bike I already have. As long as your bike can be set to your fit without messing too much with weight distribution by moving you too far back or forward on the bike (and it sounds from what you say like works fine) I think it becomes almost entirely an aesthetic issue about stem rise. If your friends really think you need a bigger frame, maybe they should buy you one :).
