ROTOR Track Axle With Spider | Maximum Stiffness and PerformanceElevate your track performance and dominate the velodrome with the ROTOR Track Axle with Spider. Engineered specifically for the rigorous demands of track and fixed-gear cycling, this premium spare part is the core of a powerful, efficient, and responsive drivetrain. Designed for athle... moretes who refuse to compromise, this axle assembly provides the ultimate upgrade for achieving maximum power transfer and optimal biomechanics. It stands as a testament to precision engineering, ready to transform your crankset into a high-performance machine.The key to its superior performance lies in its intelligent design. This component integrates seamlessly into ROTOR´s modular crankset ecosystem, offering unparalleled stiffness and a significant reduction in weight. Every pedal stroke is converted directly into forward motion, eliminating power loss from flex, which is critical during explosive standing starts and high-cadence sprints. A 30mm axle makes the crankset stiffer and lighter. A low Q-factor of 140mm ensures a perfect position on the bicycle for TRACK and Fixed users, promoting a more natural and powerful pedaling motion. This narrow stance not only improves ergonomic efficiency but also enhances aerodynamics, giving you a competitive edge when every millisecond counts.Built with ROTOR´s renowned Alu7075 technology, this track axle achieves an exceptional stiffness-to-weight ratio. The advanced aluminum construction ensures robust durability to handle the immense torque generated in track cycling, all while keeping your bike´s overall weight to a minimum. The integrated spider design further enhances rigidity and simplifies the setup, providing a solid and reliable platform for your chainring. Whether you are a competitive racer or a dedicated fixed-gear enthusiast, this axle is the definitive choice for unlocking your full potential. Experience immediate responsiveness and a connected feel to your bike like never before.Axes & Compatibility:This axle is the heart of your high-performance track crankset, designed to be compatible with ROTOR´s innovative modular systems. It allows you to build a crankset perfectly tailored to your needs, fitting popular bottom bracket standards for wide-ranging frame compatibility. Upgrade your ALDHU or Vegast crankset for dedicated track use or build your ultimate fixed-gear machine from the ground up with this essential component.Specifications:- Crank Axle Compatibility: No- Crank_axle_compability: - UBB Compability: ALDHU, BSA, ITA, Vegast- BCD: No- Crank Length: No- Axle Width: 30 mm- Axle Material: Aluminum- Number of chainrings: No- Technologies: Alu7075- Compatibility: ALDHU, BSA, ITA30- Compatible with: No-- Discipline: Track
