ive had 3-4 myself.... they are completly awsome, never skipped...... the only thing i dont like about them is the loose ring that is supposed to be mounted between the crank and the freewheel. EDIT: i want to add that the last one i ran for 8-9 months with no bashring and no bashguard... Ive hitted the freewheel plenty of times on missed taps and pedalups.... still running smooth
