ALUGEAR Round 1X AERO Chainring for 110 BCD 5-Arm Cranks
A lightweight AERO-machined round narrow-wide 1x ring for 110 mm BCD five-arm road and gravel cranks, offered from 36T right up to 60T. Ideal for converting a classic road crank to a clean single-ring setup.
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.
Eight anodised colours
Choose from black, silver and six bright anodised finishes to match or contrast with the rest of your build.
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.
