Just another bike fitting question...(6 posts)

Just another bike fitting question...SamDC
Jul 31, 2001 10:21 AM
I'm considering purchasing a road bike in the next month or so (just finished grad school and is pending on if I find a job). I've been doing some research on the web and have figured that the closest correct frame size would be a 54 cm. I'm 5'10'' but have a 31'' inseam so would I have any stand-over issues? Would a 56 cm frame be a better fit? Thanks for any info!

as there are other variables to consider.

Some bike's are measured center to top, some are measured center to center, so consequently a 55 Lemond is equivilant to a 56 Trek. It can vary model to model.

There is evidence that top tube length is at least as important as standover height (some say more important). Manufacturers vary widely as to to tube lengths. This will impact riding comfort & fit more than standover height.

Another key variable (interrelated to top tube length) is seat tube angle. The higher the seat tube angle, the more upright the rider. This affects seat tube length & comfort.

There are several good sites on the web for determining fit. You can do a search in this site on Bike fit & probably get the links.

If you have the money ($50 to $100) I would recommend you get a complete fitting done by a Serrotta fit specialist. They will give you, by bike model, which bikes fit you. If you end up buying from them, they usually give a credit for the cost of the fit. This will take the guesswork out. Remember that you will ride longer, harder & more enjoyably if the bike fits.

Good luck.

If you're in the D.C. area, as your name suggests, try Spokesbill

in Alexandria, 703-820-2200, Oakton, and Belle Haven. It's a great shop that sells (and fits) an awful lot of Serottas (and Sevens, and Treks, and Bianchis, etc.), and they have some Serottas to test ride. The Alexandria shop is right off of 395 on Quaker Lane.

I think someone beat me to the answer.

Another thing I thought of is Test ride as many bikes as you can. There is a great article on how to test ride a bike on

Good luck & let us know what's happening during your search. (We all live vicariously). It's a good fix for my own bike lust.
