Quick fit question...(4 posts)

Quick fit question...daneil
Aug 23, 2002 12:42 PM
There is a bike that i'm very interested in, the only problem is that the standover height is rather close to my own standover, in shoes. In my bike shoes, diadora syncros, my inseam measures 32". The standover is 31.75". I normally wouldn't even ask this but the tt length is pretty much spot on at 546mm when I need between a 640 and 650mm tt. Without the Syncros my inseam hovers around 31.7". Would this bike be considered too small for me? I can't test it (the perils of buying used to save some $) so i figured that I'd do the next best thing and ask you all. And just so you know the current owner is aprox. my dimensions at 5'6" and a 32" inseam. Just wondering what you all think.. Thanks alot, you guys have been great about helping me through this new bike mtn-road transition.

How many times do you actually stand that way?brider

When I got my first Softride, I was concerned at the stand-over height. It was demonstrated to me, however, that 99% of the time you'd have a foot clipped in while standing on the other foot, and the back of your thigh is what's resting on the top tube. For a beam bike, that's not uncomfortable at all.

But you give some conflicting wording here: You say the TT length is spot on, at 546mm, but you need 640-650mm? Sounds then like it's 100mm too short (or you mistyped that). In any case, if the bike appears to fit, and it's a good deal, then go ahead.

IMHO if you can stand over the bike flat footed with your road shoes on,it will be fine. Just make sure the top tube is a reasonable fit so you can use a standard seatpost (non-forward type),and about a 100mm average stem. If you are planning on racing,I would go with something a little smaller though.
Sounds like it's too big, not too smallKerry

Your info on TT length is totally confusing, and besides, you have to take into account seat tube angle to know if the top tube length is right. If you're resting on the top tube in stocking feet, it sounds like the frame is 2-3 cm too big, at least. You should look at one of these fit calculators:
