i would like to buy and build up my first 2nd hand full suspension frame.Providing the linkage is all ok and the shock is not leaking what other pitfalls should i expect to come across..?.Will i be able to fit cable disc brakes and how does the rear triangle movement affect gear change / chain slack / and the brake cable tension anyhow..?
