Aero, Narrow-Wide & Custom

Chainrings for ROTOR Aldhu, Vegast, or InSpider power meters

Get the most out of your Rotor crankset with CNC-machined chainrings from The Mechanic Parts. Whether you’re looking for an aerodynamic TMP Rotor narrow-wide chainring for your 1x beach bike, or a flawlessly shifting 2x setup for your road bike, we offer the ultimate upgrade. Discover our handcrafted chainrings that perfectly integrate with your Rotor Aldhu, Vegast, or InSpider power meter, and experience unparalleled stiffness and direct power transfer.

Featured TMP Chainrings for Rotor

The Rotor ecosystem offers fantastic modular options. We machine custom chainrings with a 110 mm bolt pattern (4-bolt) for both single (1x) and double (2x) drivetrains.

TMP Aero Chainring for Rotor (1x Narrow-Wide)

Maximize your speed with our solid TMP aero chainring for Rotor. This 1x chainring integrates seamlessly with Rotor Vegast, Aldhu 3D+, and the InSpider power meter. The unique wolf-tooth narrow-wide profile with mud grooves keeps your chain firmly in place and effortlessly clears away sand. Available from small youth chainrings to massive chainrings for time trial and beach bikes.

TMP Outer Blade for Rotor (2-Pack)

Are you building the ultimate double setup? This robust TMP outer chainring for 10- to 12-speed drivetrains delivers maximum stiffness for explosive sprints on your Rotor crankset. Available from 38T to 60T. For the very best and fastest shifting performance, always pair this outer chainring with our matching TMP inner chainring.

TMP Inner Blade for Rotor (2-Pack)

The perfect chainring for your climbs. Our TMP inner chainring is CNC-machined for flawless power transfer and seamless compatibility with your Aldhu, Vegast, or InSpider crankset. Available in a range of sizes from 34T to 46T. Quick and easy to install using standard chainring bolts.

TMP’s Technical Edge for Rotor

A TMP chainring for Rotor is not a standard replacement part, but an extremely stiff, handcrafted upgrade. Cyclists who ride with a Rotor crankset benefit from specific advantages:

  • InSpider & Aldhu Perfection: Our rims (110 mm pitch, 4-bolt) are precisely designed to match the lines of the popular Rotor Vegast, Aldhu, and InSpider power meters. This ensures a super-sleek look and an aerodynamic advantage.
  • No Special Bolts Required: While some brands require specific, expensive mounting hardware, all of our TMP chainrings for Rotor can be mounted using standard chainring bolts. This makes installation quick and easy
  • Custom Gearsets: Are you a young rider with gear restrictions, or a powerhouse who needs a massive chainring for a time trial? While standard chainrings often top out at 52T or 54T, we mill our 1x aero chainrings up to 64T (and our outer chainrings up to 60T).

Frequently Asked Questions About TMP Chainrings for Rotor

Yes, absolutely! Our TMP chainrings for Rotor (both the 1x aero version and the 2x inner and outer chainrings) feature the specific 4-bolt 110 mm bolt circle diameter (BCD) that Rotor uses for cranks such as the InSpider, Vegast, and Aldhu 3D+. They fit perfectly, both visually and technically.

No, a major advantage of our TMP chainrings is that you can easily install them using a standard set of chainring bolts. You don’t need expensive, brand-specific bolts to upgrade your drivetrain.

Our TMP aero chainring is fully closed-cut (for minimal air resistance) and features a narrow-wide tooth profile. This chainring is intended exclusively for 1x (single) setups without a front derailleur. The standard TMP outer chainring has shifting guides and is specifically designed for smooth shifting in a 2x (double) setup with a front derailleur.

All of our featured TMP chainrings for Rotor are compatible with 10-speed, 11-speed, and 12-speed drivetrains.

Our 2x chainrings are perfectly matched for the smoothest chain transition. Although, in theory, you can combine a TMP outer ring with an inner ring from another brand (provided the 110 mm bolt pattern matches), we guarantee optimal, lightning-fast shifting performance only when you use our specific inner and outer rings together as a set.

The size of the chainring depends on many factors, such as your strength, the type of rides you take, the terrain you ride on, the weather conditions, and the type of bike. We therefore cannot determine which chainring size is best suited for you personally.

Since we design and CNC-mill all our chainrings in-house, custom work is our specialty. Are you looking for a very specific tooth count (for example, larger than 60T for a double setup) or a non-standard pitch? Simply contact us via the contact form or WhatsApp to discuss the options.
