How to mount 110/4 Absoluteblack 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.
