ABSOLUTE BLACK - SRAM 5 BOLT 110BCD ROAD CHAINRING - OVAL

HOW TO MOUNT the SRAM 110/5 OVAL CHAINRING

First, you need to remove your crank from your bike. Once removed, unscrew the five bolts that hold the two chainrings together. Remove both original rings. If you have a removable spider on the crank - remove the spider by unscrewing the three T25 torx bolts before mounting new chainrings. Locate new oval inner chainring with the small hole "timing indicator" positioned behind the 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. Our Absolute Black outer chainring has a specific hole indicator - position the outer ring to line up that hole with the crank arm. Reuse the original bolts that came with the crank and use our (provided) bolt for the hidden bolt hole when mounting both inner and outer oval rings (If you have a carbon crank with an integrated spider, reuse all five original bolts).

If you are only switching the inner chainring to oval - use all the original bolts that came with your crank. Tighten all five 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.
