Sylvan Sidekick Pro Flux Carbon All Mountain Rear MTB Wheel - 27.5" 148x12mm Boost XD

Sylvan Sidekick Pro Carbon Wheels have been meticulously engineered to deliver all the comfort and performance of our Grappler Sidekick Flux wheels, packaged into a lightweight design built specifically for Trail and All Mountain riders. The rear-tuned build features optimized drive-side stiffness and reinforced lacing to deliver crisp power transfer with minimal flex when loading the rear wheel during hard acceleration and climbing.

At the heart of the wheel is the second-generation Sidekick Pro Straight Pull hub, featuring a wider 9°/13°/18° adjustable deadband that eliminates pedal kickback, enhances suspension performance, and filters drivetrain shock and vibration before it reaches the rider. A magnetic pawl-retraction system and triple-sealed design reduce drag for whisper-quiet, fast-rolling operation.

The rear wheel utilizes the robust Flux 54 carbon rim for added durability without compromising a lively ride dynamic. Handbuilt to exacting precision with a double-butted 28-spoke build using Sapim D-Light spokes and locking alloy nipples, this wheel is backed by a lifetime free rim replacement warranty for ultimate peace of mind.
