e*thirteen Grappler Sidekick Flux Carbon DH Rear Wheel - 29", 148x12mm, 7s Integrated Cassette

The e*thirteen Grappler Sidekick Flux Carbon Downhill Rear Wheel represents a groundbreaking revolution in MTB wheels, combining the suspension and performance benefits of Sidekick anti-kickback hubs with the engineered compliance of Grappler Flux rims. Tested over two World Cup seasons by the world's fastest athletes, this wheel consistently delivers top-tier results by filtering out drivetrain shock and vibration before it ever reaches the rider.

The integrated Sidekick hub features a 3-pawl mechanism with an adjustable deadband set at 12°/15°/18°, effectively eliminating pedal kickback. This allows your rear suspension to move efficiently and predictably through its travel without fighting chain tension. Combined with exceptionally low mechanical drag and near-silent operation, this wheel helps you carry more speed effortlessly through technical terrain while allowing you to focus entirely on the trail.

The low-profile Flux Carbon rim sets new standards in compliance, strength, and weight. Its ultra-compliant engineering adds vital radial compliance and traction on rough tracks without reducing razor-sharp steering precision. Built with high-quality Sapim D-Light spokes, brass nipples, and a 32-hole configuration, this wheel balances an ultra-durable build with a lively, dynamic ride feel that puts traditional, overly stiff hoops to shame.

This premium downhill setup features a 29" diameter with a 30mm inner width, spaced for 148x12mm Boost frames. It comes specifically equipped with a unique 7-speed integrated direct-mount cassette (9-24t), making it the ultimate purpose-built gravity weapon. To ensure you can push your limits with complete peace of mind, e*thirteen backs the wheel with a 5-year hub warranty and a Lifetime Carbon Rim Warranty with free replacements.
