the diamondback is a great bike for the money. has everything you need on it and costs less than the fuse. the fuse however doesn't come with a front brake, but if that doesn't bother you than its the perfect bike. get what ever one you think will suit u better, go on their websites and look over all the parts on them and compare(weight, strength, speed, what ever u think is important.) . they're great bikes, and if u still cant decide, chose which ever one u think looks better. final opinion : i love diamondback, and truthfully, ive never riden a specialized, but they do appear do build great bikes. i'd go with diamondback just because they've never let me down in the past.
