I used to ride a FFW 18t-14t it felt alright but I didn't really like it how the chain is turning when freewheeling, now i run the screw on trialtech 23t sprocket and 18t freewheel that feels alot better even though its easier it just feels more solid because of not have the freewheel up front, 22t-16t or 17t is good for riding 24.
