Sylvan Sidekick Pro Flux Aluminum All Mountain Rear MTB Wheel - 29" 148x12mm Boost XD

Sylvan Sidekick Pro Aluminum Wheels tick all the boxes for Aggressive Trail and All Mountain riders who want pro-level performance and durability that won't break the bank. 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 is built with the robust Flux 54 Pro aluminum rim for added durability without sacrificing ride feel. Handbuilt to exacting precision with a double-butted 28-spoke build using Sapim D-Light spokes and locking alloy nipples, this wheel provides a responsive, dynamic experience.
