Quick question about frame size...

I am looking at purchasing a used bike from CL. I found one guy selling the bike I want (a Trek 7000 for $200). It is a 22.5" frame size but I am only 5'10". Will it be too big for me?

I think that's probably too big. I'm 5'9" and usually an 18 inch or smaller mountain bike or hybrid would fit me.

The Trek 7000/FX frame sizes run a bit odd. I'm a textbook 54cm road bike size, and ride a 18" MTB in Trek/Gary Fisher MTB. Both my 54cm bikes fit me perfectly but have an effective top tube of 55cm. For some reason a 20" in the FX line fits me correctly, but the 20" has an effective top tube of 55.8.. so as you can see, very close.. I'm 5'9" with a 31" inseam. A 22.5 my guess is won't fit for you, as the effective top tube length has the bike at a 58cm. You don't know until you try.

It sounds a bit big for you. But nothing wrong with taking it on a test ride.

Bikes: 2 many 2 fit here

I'd check it out in person if I were you. It may well fit. I'm barely 5'10" and all my bikes are ~58cm/23" and fit great. On all of them, I have enough standover clearance to stand comfortably flat-footed, yet I have somewhat more than a "fistfull" of seatpost showing for most comfortable/efficient pedalling.

Trek measures from the center of the BB to the top of the seat tube. Others
meassure from the center of the BB to the center or top of the top tube. Here is a link to the 7000's geometry.

Hybrids tend to have more of a MTB geometry with a higher bottom bracket. The stand over will therefor be about 1 inch possibly more then a road bike of the same listed seat post height.
That bike has a 32.2 inch stand over according to the link posted above. A road bike in that frame size (it would be approximately a 57cm) would be about a 30.5).

If your inseam is 32 it would be snug but you should be able to flat foot it.

Ride it and decide! Honest.

I like to ride more stretched out, so always find a big bike comfortable. Much better, IMHO, than trying to ride a too small bike.

If you can stand over it, and still get the front wheel an inch or two off the ground, it will probably be OK.

Using it as a commuter, you just may fall in love with a bike that seemed too big......
