ALUGEAR chainring round direct mount | 1-speed narrow-wide SRAM MTB 8-hole transmission | BOOST
Alugear is based in the beautiful city of Krakow, approx. 250 km southwest of the Polish capital Warsaw. The focus is on the development and production of drive components for bicycles. The entire production cycle, from the initial design to the finished product, is carried out entirely by Alugear in Poland. This is the only way to guarantee consistent product quality with low manufacturing tolerances. Alugear has developed universal teeth for its chainrings that work smoothly with various 11-speed and 12-speed chains. In addition, the chainrings are now also compatible with SRAM Transmission drivetrains. The flat aero design is perfectly adapted to the shape of the SRAM Quarq XX1 spider.
narrow-wide tooth profile
To keep the chain securely in position even without a chain guide, the teeth have a special profile consisting of alternating narrow and wide teeth. The teeth are also shaped so that in muddy conditions the chainring is able to remove the mud itself. Dirt and mud are therefore effectively removed when the chain runs over and friction in the drivetrain is minimized.
Direct mount assembly
The chainring is mounted directly on the crank arm and replaces any spider that may have been present previously. The result is a tidy look that saves weight and offers excellent stiffness at the same time.
