Trek Sizing vs. Fisher Sizing
I'm use to riding a 17.5" on the Gary Fisher line. I was looking at the Trek 3700 recently and I noticed they're sized in 13,16,18,19.5, etc. Would the 18 fit the closest to the 17.5 in the fisher line?
Look up your bike on the trek website, then look up the gary fisher.
check the model and the "fit and sizing" info , it gives all the dimensions for each so you can compare.
right under the center of the bike, is a button that says fit and sizing.
Older than dirt
18 should work well. GF's tend to run long in the top tube and Treks tend to run smaller. Like you, I ride a 17.5 GF and an 18" Trek is perfect.
