This size is right for you (30T would be too slow).How to mount super compact 46/30T & 48/32T 110/4 Oval chainrings:First, you need to remove your crank from your bike. Once removed, unscrew the 4 bolts that hold two chainrings together with a T-30 torx key. Remove both original rings. For 46/30T - Start by placing big chainring on the crank. There is only one way to do it. Next locate triangular mark on inner circumference on the small chainring and make sure it will sit behind the crank. Small chainring has also integrated spacers on one side. Those spacers need to enter into the crank mounting holes. 30T chainring is provided with 2x M5 bolts (Torx T-25) and 2x M7 bolts (torx T-30). Lock both chainrings in place using provided bolts and torque M5 to 4-5Nm and M7 to 5-7Nm. For 48/32T - Same procedure applies except that 32T chainring comes with 4x M7 bolts (torx T-30).Absolute Black always recommends using a new chain when fitting new chainrings.This ground breaking construction has patents pending in several countries around the World.
