I have a T-Pro frame in my garage and i am building it up, the first things i need are cranks, and would not mind if a few people could give me ideas on what i need... I know i need... cranks arms, freewheel,chain,chainring and a bottom bracket. I would prefer for the cranks arms to be Tensile, but could have others depending on what other people think. For example, what bottom bracket do i need? please help me... thanks, Lewis!
