BOLTS

For Outer chainring please order "Long bolts" from us OR our Bolt Covers

Changing Inner chainring only? use original bolts

Material & Finish

cnc machined 7075 Txxx Aluminum. Long-lasting construction. Type II anodizing


IMPORTANT:

*Ramps on big rings are specially configured for combinations: 50/34, 52/36, 52/38, 53/39T

* 34t Premium Series inner chainring is not compatible with power meters which use circular spider (SRAM Quarq, Power2Max, etc) . For those power meters please choose our Silver Series 34t inner oval.

*If you wish to use other configuration it will also work, but shifting will be slower and may require more "adjustments" of front dérailleur to be acceptable. Also remember that front dérailleur can only accept 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:

*One of a kind 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 excellent strength to weight ratio


How to mount 110/4 absoluteBLACK round chainrings:

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 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 chainring has a specific shape of mounting tabs so it will only fit one way on the new version of cranks arms (for older cranks locate the recess on the chainring behind the crank arm).

If you are only changing the inner chainring - use the original bolts that came with your crank. If you are replacing a pair of rings, you will need a set of regular ‘double’ chainring bolts or our set of Bolt covers (buy bolt covers that are right for your crank model). Tighten all four bolts with force of about 5-7Nm. Mount your crank back to the bike. If you were changing outer ring size - you need to also adjust front dérailleur.



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