I just scored a mountain bike tandem from a friend (an old, purple Specialized "Deja Two"), my first tandem. I'm not sure who I'm going to ride this thing with, but I think it will be a lot of fun.
I don't intend to ride this thing in the dirt. At the moment, its fitted with some nice cross-tires. But can I put lightweight, narrow tires on it? I'm thinking of a pair of Specialized Fat Boys, which are 1.25 slicks. Will they let the bike shed some weight and make it more zippy on the road, or are they an invitation to an accident?
