lol, hydraulic disc brakes are a nice option if your mountain biking or always riding in wet conditions, perhaps in the uk with all the rain it's a more of a necessity. I just bought my 2nd bike. I bought a $30 bike off the street to bring it back tolife! Honestly, it's been quite fun.
Why do you want/need a 2nd bike? Just to say you have 2 bikes is kind of silly; I would give us information on what type of riding your planning to do with it and people could advise you better. also if your not looking to do a different type of riding and just looking to upgrade to a higher end model, tell us that too
