I'm considering purchasing a very clean used 1998 Cannondale XR800 for road use. It is a cyclocross bike that is now equipped with good aftermarket road tires. I'm curious how people think this bike would work out for long distance road riding. It has a longer wheel base which I think I would like but the fork is aluminum and pretty stiff, as is the frame. Would the longer wheel base along with some softer tires compensate for this for stiffness. It feels ok around the block but how will it feel after 50 miles? Thanks.
