Description:AL-7075-T6 chainrings are cold-formed and CNC'd with chainring ramps and shift pins. For 2003 all Truvativ XC chainrings have new chamfering and disengagement features for easier, chainsuck-free downshifting. These new chamfers, with the help of some tweaked rivets, also greatly improve the upshift. Chainring ramps and shift pins ensure smooth shifting too. Outer 44T rings are now 4mm thick. 2003 Trushift rings are backwards-compatible with our 200 series rings. Four-bolt pattern. Use with 9-speed chains.
