NSpider is a power meter for all types of bicycles and for all types of cyclists. INspider is a lightweight power meter integrated in the Spider, which provides a reliable, versatile and advanced watt measurement system. It is compatible with ROTOR's Q RINGS® oval rings and all modular ROTOR cranks, both 1x and 2x, street and MTB systems.

INspider has a battery pack with coated electronics and a strong seal for water resistance to measure performance from inside the spider. Combined left-right data is sampled in order to precisely record the output power, the cadence, the optimal chainring angle (OCA) and a recommendation for the optimal chainring position (OCP). And via ROTOR's in-house software TORQUE 360, the torque curve is analyzed during one pedal revolution.

Inspired by great victories
VEGAST® is inspired by the legacy of ROTOR racing and commemorates the three historic victories of the Grand Tours - Tour de France (2008), Vuelta España (2011) and Giro Italia (2012). ROTOS's new crankset is named after three of the highest climbs in these legendary races: VE leta - GA libier - ST elvio. So you can challenge yourself on the steepest bike ascents.

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

Direct mount technology has a proprietary spline interface that connects the crank arm, axle and chainring, allowing you to easily assemble and disassemble your crankset with just one screw.

In combination with Q RINGS®, the OCP mount technology allows you to set your optimal chainring position (OCP) in steps of one degree to precisely configure your unique OCP and to maximize the performance for your particular pedal style.

VEGAST® was manufactured using expert CNC processes and includes ROTOS's Trinity drilling system with three inner holes from the axis to the pedal. This offers the double advantage of an exceptionally light crank with superior stiffness for the most demanding rides.
