Important

• Ramps on big rings are specially configured for combinations: 50/34, 52/36, 52/38
• If you wish to use other configurations, it will also work, but shifting will be slower and may require more "adjustments" of front dérailleur to be acceptable. Also, remember that the front dérailleur can only accept a max 16T difference between 2 chainrings - this is how Shimano and Sram designed them.
• Absolute Black always recommends using a new chain when fitting new chainrings.

Advantages of Absolute Black Road Round Chainrings:

• It of a kind of look
• Super stiff design due to thicker, 5mm construction
• Bespoke Absolute Black 4 / 6 point ramp and recess shifting design shifts as crisp as original
• Finest design that provides an excellent strength-to-weight ratio

How to Mount 110/5 Bcd Round Chainring:
First, you need to remove your crank from your bike. Once removed, unscrew the five bolts holding two chainrings with a T-30 torx key. Remove both original rings. Locate the new inner chainring with the triangular timing indicator 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 also have a triangular timing indicator - position this indicator behind the crank arm. If you are only changing the inner chainring - use the original bolts that came with your crank. If you change a pair of rings, you will need a set of regular 'double' chainring bolts. Tighten all five 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.

All Absolute Black products are designed in the UK and manufactured in Poland (EU) to the highest quality standards.
