Right, I really cannot be bothered with my Profile anymore, the entire driver is fecked. So I was thinking, as the whole thing has locked, and I can't ride my bike properly because of it, Would I be able to run a front freewheel but still keep my Profile on the rear? I would also like to know, if new cranks, BB, chain and things are needed to run a FFW? Atm I am running a standard Onza crankset, standard Onza BB, and KMC Kool chain. Thankyouu, EDIT: And the FFW I want is this one http://www.tartybikes.co.uk/product.php?pr...;category_id=16 , an Echo TR. ...if that makes any difference whatsoever?
