How to mount 104bcd Oval chainring:

You may need to remove crank from the bike. Once removed, unscrew 4 bolts that hold original chainring. Position absoluteBLACK oval chainring in front of the crank spider in the way that 4 protrusions on the chainring holes fit directly into the crank tabs. The triangular mark on the inner circumference of the chainring should also sit directly behind the crank arm. Use provided 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.
