ALUGEAR chainring ELM oval Direct Mount | 1-speed narrow-wide SRAM MTB 8-hole | 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, but the range of products also includes, for example, Ahead caps.
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.
ELM
The original Alugear design.
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 the possible previous spider. The result is a tidy look that saves weight and offers excellent stiffness at the same time.
Oval shape
The ovalization of the chainring increases performance by varying the drivetrain and optimizing resistance. When pedaling with the legs, the natural strengths and weaknesses are harmonized. This results in better use of the stronger muscle groups and compensates for the weaker muscles in the work stroke (lower stroke).
Boost
Due to the chain lines used, the chainring is suitable for Boost frames with an installation width of 148 mm.
