Bolts

  • For outer chainring please order "Long bolts" from us OR our Bolt Covers
  • Changing Inner chainring only? Use original bolts


What size should I choose?

  • 34T inner chainring should be used with 50T outer ring
  • 36T inner chainring can be used with 50 or 52T outer ring
  • 38T inner chainring should be used with 52T outer ring
  • 39T inner chainring should be used with 53T outer ring

 

IMPORTANT

Ramps on big rings are specially configured for combinations: 50/34, 52/36, 52/38, 53/39T
34t Premium Series inner chainring is not compatible with power meters which use circular spider (SRAM Quarq, Power2Max, etc) . For those power meters please choose our Silver Series 34t inner oval.

If you wish to use another configuration it will also work, but shifting will be slower and may require more "adjustments" of the front derailleur to be acceptable. Also, remember that the front derailleur can only accept a maximum 16T difference between two chainrings - this is how Shimano and Sram designed them.

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

HOW TO MOUNT 110/4 ABSOLUTEBLACK ROUND CHAINRINGS


First, you need to remove your crank from your bike. Once removed, unscrew the four bolts that hold the two chainrings together with a T-30 torx key. Remove both original rings. Locate the new 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. The Absolute Black outer chainring has a specific shape of mounting tab so it will only fit one way on the new version cranks arms (for older cranks, locate the recess on the chainring behind the crank arm).

If you are only changing the inner chainring - use the original bolts that came with your crank. If you are replacing a pair of rings, you will need a set of regular ‘double’ chainring bolts or our set of Bolt covers (buy bolt covers that are right for your crank model). Tighten all four bolts with force of about 5-7Nm. Mount your crank back to the bike. If you were changing the outer ring size, you need to also adjust your front derailleur.
