YO! Im going to change from square taper to isis and now is a good time because I need a new freewheel and cranks anyway. Right, im not sure what freewheel,cranks and BB to go for but I need to try and keep the cost down because I have £45 at the moment and I get £10 a week which kinda sucks but I have exams so not much time for work Please could you give me advice on what cranks,freewheel and BB to buy. Thanks- ~Matty
