• 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 Benefits of Oval Chainrings

Oval chainrings improve the efficiency of the pedaling cycle by adjusting resistance throughout the pedal stroke. This allows riders to produce power more effectively during the strongest part of the stroke while reducing resistance during weaker phases.

• Smoother Power Delivery: Optimizes force distribution during pedaling

• Improved Climbing Efficiency: Helps riders maintain momentum on steep climbs

• Better Pedal Stroke Efficiency: Reduces dead spots in the pedaling cycle

• Enhanced Rider Endurance: Lower muscle fatigue during long rides

• Reduced Knee Strain: Supports a more natural and comfortable pedaling motion
