    Frame Size choice

    I'm 6'2 with 34.6 inch inseam and I tried out the Trek FX series and their 20 is a bit small for me and the 22.5 is a bit big on the other hand... they do look significantly different. The staff in LBS suggested the bigger one although I felt it is kinda big for me.

    Should I go with the bigger one or smaller one? I wish there is a 21 size...

    I had the same problem. You are about 2 inches taller than I am and I would think the larger model would be perfect. I'm 6 and 32 inseam and the 20 fit pretty good. The XL model was way too big. Although at first I thought the 20 would be a little too small (just a little) but I've grown to love it. If I need to stretch out more in the future I can just buy a little longer stem (if you slam the stem it will move it forward too) and then maybe move the seat back, some handlebars without much of a bend. There's a lot of things you can do to adjust the fit. If the XL feels too long you could put a shorter stem on etc etc. I found the XL too big and the standover was not comfortable. Go back and take them both for a spin again. You're going to be the ultimate judge.

    Yeah, thanks.

    Not only should you take them for another spin, you should try another brand that has a frame around 21". WIth the amount of FX bikes Trek sells, it's shameful they don't offer the frames in more sizes. Stems, bars and seat posts can only do so much to improve the fit...

    Ride them both and see which feels better. If in doubt, I say get the SMALLER one.

    But, yes, switch to another brand if Brand A leaves too big a fit-gap right where you need to be.

    That's what I've been told to do as well. When you're in the middle, choose the smaller frame as it gives you more flexibility.

    I think if you are feeling cramped in with the smaller frame go bigger and adjust with a different stem. Explain your concern to the lbs and ask if they would swap out a stem for test riding.
