Oval 1x chainring · 110 BCD
ALUGEAR Oval 1X AERO Chainring for 110 BCD 5-Arm Cranks
A lightweight AERO-machined 12% oval narrow-wide 1x ring for 110 mm BCD five-arm road and gravel cranks, offered from 38T right up to 60T. A smoother-feeling pedal stroke for riders converting to a single-ring drivetrain.
Highlights
Why we rate it
Narrow-wide teeth
Alternating thick and thin teeth hold the chain securely on a 1x drivetrain, keeping noise down and reducing the risk of dropped chains.
CNC-machined 7075-T6
Milled from high-strength 7075-T6 aluminium and hard-anodised, so the ring resists knocks and wear and keeps its finish.
AERO lightweight design
Slim, heavily machined arms strip out weight while ALUGEAR's testing keeps impact strength where it matters.
12% oval profile
The ring is effectively smaller through the dead spot and larger through the power phase, helping smooth your pedal stroke on long climbs and rough gravel.
Best with a clutch mech
For the most secure 1x setup ALUGEAR recommend a clutch rear derailleur and a fresh chain fitted with the new ring.

3. Carefully cut one corner of the sachet open along the diagonal cut lines.
4. You can carefully pour the sachet straight into the top of the bottle. Or using the box, fold the inside of the lid together using the printed lines as a guide and use this as a funnel to pour the powder into your bottle. (Please see our video for full instructions on this.
5. Screw your spray trigger back onto the top of the bottle. Ensure it’s tight!
