e*thirteen Sylvan Sidekick Pro Flux 43 Aluminum All Mountain Front Wheel - 29", 110x15mm Boost, Black

The e*thirteen Sylvan Sidekick Pro Flux 43 Aluminum All Mountain Front 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 trail bikes, this premium 29-inch front wheel brings together e*thirteen's revolutionary anti-kickback hub technology and a highly optimized, front-specific aluminum rim layout to provide a smoother, less fatiguing ride feel that transforms your local singletrack.

The centerpiece of this wheel build is the second-generation Sidekick Pro Straight-Pull Front Hub. Designed to complement advanced rear-hub setups, this straight-pull hub configuration sheds up to 160g over previous generations while offering exceptionally low internal drag and whisper-quiet trail operation. By allowing the chassis to stay completely independent of drivetrain forces, Sidekick technology filters out harsh background drivetrain shock and structural vibrations before it ever reaches your hands, letting you hold technical high-speed lines with supreme confidence.

Laced up to the hub is the front-specific Flux Pro 43 Aluminum Rim. Built from a premium AL 6069 aluminum alloy with a high-strength welded joint, this rim features an application-specific ultra-low profile design. By deliberately engineering radial compliance into the rim, it deflects vertically over harsh square-edged rocks and repetitive trail chatter, acting as an integrated layer of small-bump suspension. This ensures maximum front-tire traction and tracking predictability without sacrificing necessary lateral steering precision. A broad 30mm inner width stabilizes modern wide-casing trail tires, allowing you to run lower tire pressures for maximized cornering bite while broad hookless flanges protect against rock strikes and pinch flats.

This 29" front wheel features a weight-saving and compliance-boosting 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. Coming in at a nimble 830g and featuring standard 110x15mm Boost spacing with a 6-bolt disc layout, the Sylvan Sidekick Pro Flux 43 wheel is backed by e*thirteen's robust 10-year warranty on the hub body and a premier Limited Lifetime Rim Warranty for total long-term security.
