HOW TO MOUNT 110/5 OVAL CHAINRING:

First you need to remove crank from the bike. Once removed, unscrew 5 bolts that hold two original rings together with T-30 torx key. Take off both original chainrings. Position Absoluteblack oval chainring in same place where the big chainring was. Please note that small indicator on the chainring Must sit behind crank arm - same way as original chainring indicates its position (If you are mounting it to the crank with one hidden bolt, then the small indicator has to be exactly opposite to the crank arm to assure correct oval position). Use provided AB bolts to lock the chainring in place using T-30 torx key with force of about 5-7Nm. Mount your crank back to the bike. Done

Always use a new chain with a new chainring.
