Q Rings MTB BCD100x4

Designed exclusively for BCD100x4 spiders and ROTOR INspider MTB power meters.

ROTOR Q RINGS MTB BCD100x4 are our most advanced chainring solution for 100x4 MTB cranksets and the perfect match for INspider MTB power meters.

The oval design of Q RINGS optimizes power delivery throughout the pedal stroke by reducing resistance during the dead spots and maximizing power transfer during the strongest phase of the pedal rotation. This results in a smoother and more efficient pedaling experience.

In addition, their optimized design reduces chainring weight by up to 40% while allowing riders to benefit from integrated power measurement when paired with an INspider MTB power meter.

These chainrings are fully CNC-machined from a solid block of aerospace-grade 7075-T6 aluminum alloy. This manufacturing process enables an exceptional stiffness-to-weight ratio, ensuring maximum power transfer and durability in demanding MTB conditions.

They also feature our patented Universal Tooth® technology, providing full compatibility with Shimano® and SRAM® 11, 12 and 13-speed drivetrains, including SRAM Flattop® chains. This guarantees seamless shifting performance and broad compatibility with virtually any modern MTB drivetrain.
