So I know several riders around here who are unloading their 29er's and buying MTB's with 650b wheels/tires. I love my Scott Scale 950 and am not at all interested in replacing it, besides which its only three years old. One of my MTB buddies and I were talking about the advantages of the 650b setup and it occurred to me that since my bike has disc brakes I could just buy a set of 650b wheels/tires and put them on my current bike. The guy I was talking with had recently taken delivery of his new Trek 650b bike after selling his 29er. When I mentioned this, he looked seriously pissed. Neither of us could think of any reason why my idea won't work, even after talking to a couple of bike mechanics who also couldn't see any reason why just changing wheels/tires wouldn't work. I could even run the 29 on the front and the 650b on the rear, sort of like Trek's old 69er bike. I can't believe this is a totally original idea, somebody must have thought of this before me, maybe someone here.
So, anybody here know of any reason why this wouldn't work?
