Recently had my bike stolen, and having little money I’ve bought a used one as a replacement. It’s fine enough, but needs a little fine tuning. The main issue is that the hand-brake at the front wheel is a rim brake.
Is there a way to install a disc brake on the front wheel instead, or would I have to change the entire frame?
Also I’ve only ever done basic maintenance, but now I need to do a bit more (install a new set of gears). Does anybody have a recommendation for a good manual?
