Our Premium Shimano 110/5 (bolt pattern) and Sram Force/Red oval chainrings are designed for pre-2014 cranks like Shimano Dura-Ace FC7950, Ultegra FC6750, Shimano 105-5750, Sram Force/Red and many more with 5 bolt fitting. These are the finest shift-able oval chainrings on the market.

How to mount 110/5 Oval Chainring:

First, you need to remove your 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 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. 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 a 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.
