Highlights
Why we rate it
Fits 104 BCD cranks
Bolts to the common 104 mm four-arm pattern, opening up a huge range of MTB-style and gravel cranks for 1x use.
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.
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.

Sachet Instructions

2. Fill up to the shoulders of the bottle with 1 litre of lukewarm water for faster formula activation!
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!
6. Shake the bottle vigorously for 30-60 seconds to activate the formula. If you notice any undissolved powder simply keep shakin’ it!
