I own a Gary Fischer hardtail MTB with 26-1.75 tires on them. My wife recently got a new roadbike and no longer rides her hybrid which have 700-28 tires on them. I am doing a metric century this coming weekend and was thinking of ways to increase my speed (with the use of my MTB).
Do you think I can switch the hybrid tires to my MTB? I believe the OD of the tire is about the same so the only real issue would be to re-adjust the brakes to grab a skinnier rim. Both my MTB and my wife's Hybird have the same 7-speed rear cassette so I think the gearing will be no issue.
Your collective thoughts???
