ALUGEAR chainring oval Aero Direct Mount | 1-way 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 manufacture of drive components for bicycles. B. Ahead caps on offer.
The entire production cycle from the first draft to the finished product is completely realized by Alugear in Poland. This is the only way to guarantee constant product quality with low manufacturing tolerances. The flat aero design gives the crank an extravagant look.
narrow-wide tooth profile
In order to keep the chain securely in position even without a chain guide, the teeth have a special profile of narrow and wide teeth alternating. The teeth are also shaped in such a way that the chainring itself transports the mud away very well in muddy conditions. So dirt and mud are effectively removed when the chain overflows and friction in the drive train 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 at the same time offers excellent rigidity.
The ovalization of the chainring increases the performance by varying the drive train and optimizing the resistance. When you kick your legs, natural strengths and weaknesses are brought into harmony. In this way, better use of the stronger muscle groups is achieved and a balance is created in the weaker muscles on the way to work (shorter stroke).
Due to the chain line used, the chainring is suitable for Boost frames with an installation width of 148 mm.
