Silver Series line of chainrings is a simplified version of our state-of-the-art Premium line. They use same aluminium, teeth and shifting ramp design. However they are less machined out from the front for easy maintenance and cleaning.

How to mount Silver Series line 110/5 Oval chainring:
First, you need to remove crank from your bike. Once removed, unscrew the 5 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. AbsoluteBlack Outer chainring has a dimple mark – position the outer chainring to line up that dimple 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 chainrings, you will need a set of regular ‘double’ chainring bolts (Long bolts in our offering). Tighten all five bolts with force of about 5-6Nm. Mount your crank back to the bike. You may also need to adjust the front derailleur upwards by 2-4mm.
All Absolute Black products are designed in UK and manufactured in Poland (EU) to the highest standards of quality.
