Absolute Black Oval Road Chainring 2X 110/5 (50T/52T) (Not For SRAM)-Red

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

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 pedalling 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 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 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 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.

Performance & Pedaling Efficiency

The oval profile of this chainring is engineered to maximize the power phase of your pedal stroke. This allows riders to generate smoother and more consistent torque throughout the rotation. By optimizing the pedaling mechanics, the chainring helps maintain a steady cadence when climbing steep gradients. It also reduces the chances of leg fatigue and muscle strain during long rides. The result is a more efficient cycling experience where power is delivered more smoothly and consistently.
