Just got a Fishbone Kong Fu and the chrome sun box rims are really corroded and need replacing, any recommendations? just something cheap not bothered about colour. Also the seatclamp is really faded and its got a ultimate hardware seatpost for rails and a primo flatland seat with padding but it weighs a ton and would like to replace them, I assume I can use new school stuff? I just tried a new school post and it fitted. The bike weighs a ton but hopefully will be able to shave a bit of weight off it, plastic pedals etc{and to save shins) Thanks
