BOLTS

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

Changing Inner chainring to oval only? use original bolts

Material & Finish

cnc machined 7075 Txxx Aluminum. Long-lasting construction. Physical Vapour Deposition

Ovality

Optimized to each size separately. 34T- 6.5% ; 36T, 38T, 39T- 11.4%, 50/52/53T - 10-11.2% ; Timing of 108 -110.5° after TDC (top dead center) - Ideal for road climbing. Patent Pending

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 ABSOLUTEBLACK ROAD OVAL CHAINRINGS:

*One of a kind special oval shape that helps you climb easier and faster (Patent Pending)
*Over 15% stiffer than Rotor Qrings due to thicker, 5mm construction
*Bespoke Absolute Black 6 point ramp and recess shifting design shifts better than any other brand and model of oval chainring
*Finest design that provides excellent strength to weight ratio
*You will not "feel" the oval shape while pedaling
*Your pedaling action will feel smoother
*Helps reduce stress on knees and helping your legs remain fresher for longer
*You will be able to maintain better cadence while climbing
*Reduces possibility of leg cramps
*You will reduce chainring/cog shifts by at least 15%

HOW TO ADJUST FRONT DERAILLEUR WITH ABSOLUTEBLACK ROAD OVAL CHAINRINGS

To proceed with the adjustment you will need 2mm and 5mm allen keys.

Trouble shooting:

*If your derailleur overshifts the chain when moving from small ring to the big ring, it means your "gap" is greater than 2mm when chain is on big chainring (see video). You may need to reduce the gap. Your front derailleur may also be too high compared to what is advised on the video. Last thing to check is if your cage is parallel to the big chainring face.

*If your front derailleur is hesitating to shift from small to the big ring then two issues may be present. The "gap" may be too small (It has to be 2mm - see video) or your cage is not parallel to the big chainring face.

HOW TO MOUNT 110/4 9100 / 8000 OVAL CHAINRING: (SAME INSTRUCTION AS FOR 9000/6800 CRANKS)

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 oval 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 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 or our set of Bolt covers. Tighten all four bolts with force of about 5-7Nm. Mount your crank back to the bike. You may also need to adjust the front derailleur slightly.
