Yes, you will need new hubs. There will be two small mounting holes on the fork and rear triangle if it will take discs. I don't really have any experience with adapters...not necessary for all brakes.Lewis63 said:ok so I might be interested in disk brakes for my bike but how do I know if my bike has the mounts for them? what should I look for on the rear triangle? how many holes? Pictures would be nice if anyone has any showing a disk brake compatible and a not compatible.
also what your take on all these I adaptors I keep reading about. Are they any good?
do I need special hubs for disk brakes?
thanks for the help
