Thanks' guys. I should have specified on tire size closer before. I have a Marlin 5 for my wider tire needs. My Trek 400 currently has 32's on it and I like it a lot. I wish it was 5 lbs lighter .I have my Miyata set up with the original 27x1-1/4 as well as a 700c set with 38's. Anyway,I really like the 38's on my Miyata which got me thinking how great it would be to have a bike as light as my Lemond, currently 18lbs, but still be able to take up to a 32 and optimistically, maybe a 35mm.
Honestly, I feel pretty blessed to have some really nice bikes that I bought real cheap but I can't help thinking about the next one.
