Bottom bracket preload adjuster ring for ALUGEAR cranks

INFORMATION

ALUGEAR Stellar cranks are meticulously CNC machined and can be anodized in eight vibrant colors, adding a striking visual flair to your bike while delivering impressive technical performance.

In recent years, the approach to selecting crank length for mountain bikes (MTB) has undergone significant changes. Following modern trends in the bike industry, the company ALUGEAR has designed Stellar cranks for MTB, specifically focusing on shorter crank arms. These are designed for use in disciplines that require enhanced control, maneuverability, and stability on challenging terrain.

This high-performance crankset is tailored to deliver unparalleled reliability and efficiency across these demanding environments, ensuring that riders can confidently push their limits.

For removing the crank arm is used self-extracting hardware.

We carefully designed our cranks and threaded the Crank Bolts and Integrated Pullers so that they would minimize the possibility of the Crank Arms coming loose.

The ALUGEAR Stellar cranksets are produced from durable materials, giving them exceptional longevity. Keep this in mind during assembly, maintenance, or operation of the component. Due to the material's resilience, most minor damages will not harm the cranksets. However, when handling the cranksets, it is crucial to be extremely careful during operation and maintenance, using only those tools that are specifically designed for installation and service tasks

Component Compatibility: Ensure that all components are compatible with each other and fit your bicycle
