So, for two years I've wanted a cross check. Now, I'm down to actually getting one, but I'm torn between the 54cm and 56cm frame and which one would fit better. Of course, it would help if the local dealer had one on hand for a test fit, but such is not the case. Because of that, I've been relegated to research and comparative figures; comparing Surly's fit chart, my current rides, and my body measurements. I'm 5'7.
The 54cm frame has a TT of 22 inches while the 56cm is about 22 1/2 inches. I'd be fine with the reach of either. My '82 Trek 614 has a TT of 22 inches, but the seat is adjusted all the way back on the rails for me to fit comfortably with drop bars and an 80mm stem. I could even go 90mm on the stem and move the seat forward a bit and still be comfortable.
The standover clearance on the 54cm 31.2 inches while the 56cm is 31.9.....a difference of about 1 1/2cm's. Not much at all until it comes to tire sizing, I suppose. Which brings me to.........
I saw a CL listing for a 56cm Cross Check complete. The fellow measures the standover clearance at 32 inches with 700cx32 tires. That would be enough for me, I believe. With riding shoes, I can stand over my early 90's Trek 520 (I'm selling) with bare 700c wheels with a little room...very little......but, enough so that I have to squat a bit to sit on the TT. It measures 33 inches of standover, in this way. Put some tires on and I'd be having to lean over the bike to get on and I wouldn't have any clearance.
Now, if I went with the 56cm and put like 700cx45's on, is this going to markedly change the standover height on the ride? I ask because I've never had tires over 32mm in size, so no experiential comparison. I mean, obviously by measurement it's a difference of a hair over 1cm, but I've no idea how much it would change things in reality.
If any of you were me, which way would you go with it and why? What would be the more important aspects of consideration? I intend to use the bike offroad on mild mtn bike trails, city trails, all round riding, and touring, if that helps in the replies.
Thanks a bunch!
