ok, so I have upgrade the wheels and aadded new brakes, cables etc. also i tweaked the derailier and it is running smooth.

the crank is super flexy and the bottom bracket seems to be rough (not smooth). I want to replace the crank and bb and add new pedals as well.

can someone pass me some info on good crank at a decent price that will work on this bike?

anything from harris cyclery?

thx!
