Important
- Ramps on big rings are specially configured for combinations: 50/34, 52/36, 52/38, 53/39T
- If you wish to use other configuration it 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 chainrings - this is how Shimano and Sram designed them.
- Absolute Black always recommends using a new chain when fitting new chainrings.
How To Mount
How To Mount Absolute Black Oval Road Chainring 2X 110/4 Shimano 9100 Rainbow
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. Locate the new oval inner chainring with the triangular timing indicator positioned behind crank arm. The bolt holes on the small chainring are recessed – so the nut heads will sit flush with the surface of the chainring - these recesses should face you when mounting the bolts. Absolute Black outer chainring has a specific shape of mounting tabs so it will only fit one way on the crank arm. If you are only switching the inner chainring to oval - use the original bolts that came with your crank. If you are switching to a pair of oval rings, you will need a set of regular ‘double’ chainring bolts or our set of Bolt covers. Tighten all four bolts with force of about 5-7Nm. Mount your crank back to the bike. You may also need to adjust the front derailleur slightly.
