IMPORTANT
*Ramps on big rings are specially configured for combinations: 50/34, 52/36, 52/38
* 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 110/5bcd round 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 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 also 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 are changing a pair of rings, you will need a set of regular ‘double’ chainring bolts. Tighten all 5 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.
All Absolute Black products are designed in UK and manufactured in Poland (EU) to the highest standards of quality.
