Tax included
The ROTOR Spidering 2025 NoQ introduces a new generation of one-piece double chainrings for 11 and 12-speed drivetrains. Lighter, stiffer, and smoother than classic 110x4 setups, it’s fully compatible with Shimano® and SRAM® chains thanks to Universal Tooth® technology.
This round version is available in three optimized configurations:
-
48/31, new for 2025, replacing the former 48/32 — ideal for climbing and gravel
-
50/34, the most versatile setup
-
52/36, for maximum performance on flat or rolling terrain
An efficient upgrade for any cyclist looking to optimize their double drivetrain, on tarmac or gravel.

ROTOR Spidering 2025 NoQ – A new era for 2x chainrings
The new ROTOR Spidering 2025 replaces the original version released in 2017. It brings full compatibility with 11 and 12-speed drivetrains, improved stiffness, lighter weight, and a cleaner, more modern design. Direct mount means no spider or bolts needed.
A lighter, stiffer and more efficient 2x chainring
Made from a single CNC-machined piece of 7075 aluminium, the Spidering 2025 saves around 30 grams compared to a standard setup using a 110x4 spider and chainrings. Fewer parts mean improved power transfer and reduced flex under load.
Universal compatibility with Shimano® and SRAM®
ROTOR’s patented Universal Tooth® design ensures smooth, secure chain engagement with any 11 or 12-speed chain — including Shimano HG+ and SRAM Flattop. A major upgrade for those mixing drivetrain components or upgrading gradually.
Now available in 48/31, 50/34, and 52/36
The Spidering 2025 comes in three finely tuned options:
• 48/31 – brand new for 2025, smoother than the old 48/32, ideal for climbing or gravel
• 50/34 – the best all-round setup
• 52/36 – for riders chasing speed and efficiency
Minimalist, technical design
Refined CNC cuts and a tough anodised black finish give the Spidering 2025 a modern look that complements ROTOR's Aldhu and Vegast crankarms. Every detail has been engineered for performance, lightness, and aesthetics.
- Direct mount for ROTOR Aldhu, Aldhu Carbon, and Vegast crankarms
- Compatible with Shimano®, SRAM®, KMC 11/12-speed chains
- Patented Universal Tooth® profile

Velo-Perso.com’s recommendation
The new Spidering 2025 is one of the most efficient upgrades you can make to your road or gravel drivetrain. The 48/31 option is ideal for climbing and long rides with steep gradients, while 50/34 and 52/36 remain strong choices for versatile and performance-focused setups.
