The INspider power meter is a result of our mission to get a power meter on every bike. It is a small upgrade with a big impact — just add the spider to any of our modern cranksets and take the guesswork out of training.

This power meter can spend one weekend on a tri bike and the next on a full sus at the bike park. It’s easy to swap, durable, and fully cross-compatible. The same INspider power meter will work with any of our current cranksets: Road, MTB, CX, or Tri, in any length (150-175mm) and any axle configuration.

Pro Tip: Paired with our aero rings and Aero Crown, the INspider looks as good as it rides. It is elegant, aerodynamic, and wicked fast.

Compatibility:

The INspider power meter is only compatible with the ALDHU, ALDHU24, VEGAST, VEGAST24, RHAWK, RRAPTOR, KAPIC, and KAPIC Carbon cranks.

Note: BB386 and BB86 frames may run into clearance issues; please call us for compatibility before ordering and check for contact before riding. 

Technical details:

The spider-based power meter uses four strain gauges to achieve accurate power readings within +/- 1%. With an all-new ambient variable calibration feature, this power meter responds in real-time to changes in temperature and atmospheric fluctuations to ensure that your data is consistent regardless of conditions. The rechargeable battery uses the same charging interface as our 2INpower and has 200 hours of battery life on each charge.

The 110×4 asymmetric bolt pattern works equally well with 1x, 2x, and MTB drivetrains. It features the same 8° chainring clocking for fully optimizable chainring positioning.

Note, especially for MTB applications: The smallest compatible ring is a 34t 110×4.

VEGAST® is inspired by ROTOR’s racing heritage to commemorate our 3 historic victories of the Grand Tours – Tour de France (2008), Vuelta España (2011) & Giro Italia (2012). Our new crankset is named in honour of 3 of the highest climbs of these iconic races: VEleta – GAlibier – STelvio.  so you can challenge yourself on the steepest of cycling climbs.

VEGAST® ‘s innovative modular system allows you to select each crank component based on your unique bike setup and physical characteristics and includes both Road & Track versions. Choose your set-up from ROTOR’s one-piece Q RINGS® or Round Direct Mount chainrings or classic spider plus oval or round chainrings.

Direct Mount technology features a proprietary spline interface connecting crank arm, axle and chainring allowing you to easily assemble and disassemble your crankset with only one bolt.

Combined with Q RINGS®, OCP mount technology allows you to adjust your Optimal Chainring Position (OCP) to within one degree increments to precisely configure your unique OCP to maximize power output to your distinct pedaling style.

Crafted using expert CNC processes, VEGAST® includes our Trinity Drilling System, with three internal holes from axle to pedal, giving the dual benefit of an exceptionally light crank with superior stiffness to take on the most challenging rides.
