Product Description
e*thirteen Sylvan Sidekick Pro Flux 54 Aluminum All Mountain Rear Wheel - 27.5", 148x12mm Boost, Microspline, Black
The e*thirteen Sylvan Sidekick Pro Flux 54 Aluminum All Mountain Rear Wheel ticks all the boxes for aggressive trail and all-mountain riders looking for pro-level handling, elite terrain tracking, and rugged structural durability. Engineered to enhance the overall performance of mid-to-long travel full-suspension bikes, this premium 27.5-inch rear wheel brings together e*thirteen's revolutionary anti-kickback hub technology and a highly optimized, rear-specific aluminum rim layout. This nimble 27.5" configuration is the definitive choice for riders running full 27.5" trail setups or those building a highly agile, hard-charging mixed-wheel (Mullet) configuration that balances quick cornering response with heavy rock-strike durability.
The defining centerpiece of this wheel build is the second-generation Sidekick Pro Straight-Pull Rear Hub. Shedding up to 160g over previous versions, this high-performance hub features an adjustable 9°/13°/18° mechanical deadband system and a reliable 3-pawl mechanism. The rapid-engaging 9° setting delivers a crisp, traditional freehub feel when technical climbing is your primary focus, while a tool-free deadband adjustment allows you to open up the mechanism on rough descents. By decoupling drivetrain forces from your rear suspension, Sidekick technology completely eliminates pedal kickback and isolates background chain feedback, allowing your rear shock to track terrain perfectly without affecting intended frame kinematics.
Laced up to the hub is the rear-specific Flux Pro 54 Aluminum Rim. Built from a premium AL 6069 aluminum alloy with a high-strength welded joint, this rim features an application-specific profile designed to offer additional structural reinforcement over its front-wheel sibling. It balances terrain-smoothing radial compliance with the increased impact resilience required to manage heavy rear-wheel casing and square-edged strikes. A generous 30mm inner width perfectly supports modern wide-casing trail tires, maximizing tire footprints to prevent tire roll under hard cornering loads, while broad hookless flanges deliver set-and-forget tubeless security and superior pinch-flat protection.
This 27.5" rear wheel features a weight-conscious yet highly durable 28-hole drilling. It is meticulously handbuilt to exacting precision using premium Sapim D-Lite double-butted spokes and Sapim Secure Lock alloy nipples, ensuring long-term tension stability and a lively, highly responsive ride quality under hard cornering. Coming in at a nimble 1040g and featuring standard 148x12mm Boost spacing, a Shimano Microspline compatible driver, and a dependable 6-bolt disc mount, this wheel is fully backed by e*thirteen's robust 10-year warranty on the hub body and a premier Limited Lifetime Rim Warranty for ultimate long-term value.
