E*Thirteen Grappler Sidekick Enduro 29" Wheel A Revolution in MTB Wheels If you're riding difficult trails, your wheels have to be tough. When your descent is long, you'll want to ride knowing you can trust your wheels. The E*Thirteen Grappler Sidekick Enduro 29" Wheel combines the suspension and performance benefits of Sidekick anti-kickback hubs with the control and comfort of engineered compliance from Grappler Flux rims. Sidekick hubs feature an adjustable deadband that eliminates pedal kickback, enhancing suspension performance and filtering drivetrain shock and vibration before it reaches the rider. Low-profile Grappler Flux rims set new standards in compliance, strength, weight, and performance. Together, these technological marvels offer increased comfort, enhanced speed and control, and a lively ride feel that puts wooden-feeling hoops to shame. Efficient and predictable suspension performance, added traction and tracking, reduced rider fatigue, and nearly silent hub operation create a more confident and immersive ride experience for both pros and enthusiasts.
