ROTOR Spidering Q-Rings 2025 – 12.5% Oval Chainring for Optimised 2x Drivetrains
The ROTOR Q-Rings Spidering 2025 marks a new era for double oval chainrings, machined from a single piece for 11 and 12-speed systems. It replaces classic 110x4 models with better stiffness, lower weight, and Shimano®/SRAM® compatibility via patented Universal Tooth® technology.
A smoother and more efficient pedal stroke
With a 12.5% ovality, the Q-Rings Spidering reduces dead spots and improves pedaling fluidity, especially during climbs and accelerations. Each rotation feels smoother and more balanced for better efficiency.
Lighter, stiffer, cleaner direct mount design
CNC-machined from 7075-T6 aluminium, this chainring is up to 30g lighter than a traditional 110x4 setup. Direct mount integration ensures better stiffness with no bolts or spiders required.
Now available in 48/31, 50/34 and 52/36
Choose from three optimal setups:
• 48/31 – new for 2025, smoother than previous 48/32, ideal for gravel and climbs
• 50/34 – all-rounder setup for versatile riding
• 52/36 – built for power and fast rolling terrain
Adjust your OCP with 5 mounting positions
