Just wanted some opinions here. If you had a mountain bike which you really liked would you buy a whole new bike just to upgrade to disc brakes? I have a 2004 Trek 6700 with v-brakes and to me it is just fine. However, everyone tells me how great disc brakes are. I am not going to add them to this bike because the price of a decent set of disc brakes is fairly high considering I would need new hubs also. So what would you do?
