How to mount 110/5bcd Round Chainring:
First, you need to remove your crank from your bike. Once removed, unscrew the 5 bolts that hold two together with a T-30 key. Remove both original rings. Locate the new inner with the triangular timing indicator positioned behind crank arm. The bolt holes on the small are recessed – so the nut heads will sit flush with the surface of the – these recesses should face you when mounting the bolts. Absolute Black outer have also triangular timing indicator – position this indicator behind the crank arm.
If you are only changing the inner – use the original bolts that came with your crank. If you are changing a pair of rings, you will need a set of regular ‘double’ bolts. Tighten all 5 bolts with of about 5-7Nm. Mount your crank back to the bike. You may also need to adjust the front derailleur upwards by 2-3mm.

- If you wish to use other will also work, but shifting will be slower and may require more “adjustments” of front dérailleur to be acceptable. Also remember that front dérailleur can only accept max 16T difference between 2 – this is how Shimano and Sram designed them.
- Absolute Black always recommends using a new chain when fitting new .
