nice one Steve.. he he he
I took through the mail in the previous century before internets and all that good stuff.
tbh, it wasnt bad, got a good general idea of what's what on a bike.
Pretty poor support, but again that was way back in the day.. I am sure
with emails and videos, you can get questions answered much easier.
As an example, every bike manufacturer builds brake calipers in a different way...
but the basics are the same: pads, pistons, diaphrams, fluid.
Home study courses will give you the basics.
I would defintely suggest buying a parts bike ( or two ), that way you
have something to play with without worrying about messing up your main ride.
I found it helpful.. as a career move... not enough.
