INspider Vegast 1X Crankset

The INspider Vegast is ROTOR’s most versatile spider-based power meter, designed for all types of bikes, riders, and disciplines—from road and gravel to triathlon and MTB. It is compatible with round and Q Ring® oval chainrings, 1x and 2x setups, and works seamlessly with any groupset, cassette, and chain, thanks to ROTOR’s Universal Tooth® technology. The INspider provides accurate dual-leg power measurement, including cadence, Torque 360, OCA (Optimum Chainring Angle), and OCP (Optimum Chainring Position), offering advanced training data. Its sealed internal electronics and long-lasting rechargeable battery ensure durability and water resistance in all conditions.

The crankset includes ROTOR Vegast® cranks, forged from 6082 aluminum and CNC-machined to deliver a superb stiffness-to-weight ratio. They feature Trinity Drilling System®, with three longitudinal holes inside each arm to eliminate excess material and reduce zweight without sacrificing strength. The 24 mm axle is compatible with Shimano® bottom brackets, making it easy to upgrade your current setup. When paired with 2x Q Ring® oval chainrings, the system helps reduce effort at dead spots (0° and 180°) and maximize power at the most effective points of the pedal stroke (90° and 270°). It's fully compatible with Shimano® 11- and 12-speed groupsets.

Designed for performance and customization, the Vegast crankset’s modular system lets you select crank arm lengths, chainring configurations (1x or 2x), and optimize your setup for your specific needs. For those seeking enhanced aerodynamics, the optional Aero Crown completes the integrated look and helps minimize wind resistance—saving valuable watts.

Ideal for road, gravel, or triathlon, the INspider Vegast offers outstanding value, combining cutting-edge power data, reliability, and high-performance engineering to elevate your ride.
