Absolute Black always recommends using a new chain when fitting new chainrings.

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 dĂ©railleur to be acceptable. Also remember that front dĂ©railleur can only accept max 16T difference between 2 chainrings - this is how Shimano and Sram designed them.

HOW TO MOUNT 110/4 OVAL CHAINRING:

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 chainrings have a specific recess to accommodate the rear edge of the crank arm - position the outer ring to line up that recess with 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. 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 upwards by 2-3mm.
