Boost Hub Conversion Kit — Front 15x100mm to 15x110mm, Rear 12x142mm to 12x148mm Key benefits Converts standard axle spacing to Boost spacing so you can use Boost wheels or hubs on compatible frames and forks. Keeps wheel and frame alignment correct while enabling wider hub spacing for improved tire clearance and stiffer wheel builds. Lightweight, durable components minimize added mass while resisting wear and corrosion for reliable performance in demanding riding conditions. What's included Front adapter: Aluminum alloy adaptor with matching washers and bolts for fork compatibility; converts 15 x 100 mm to 15 x 110 mm. Rear adapter set: 12 x 142 mm to 12 x 148 mm conversion components; black anodized aluminum parts weighing 27 g for enhanced durability and corrosion resistance. All hardware required for the stated conversions is supplied for straightforward installation on compatible bikes. Specifications Front conversion: 15 x 100 mm > 15 x 110 mm (includes adapter, washers, bolts) Rear conversion: 12 x 142 mm > 12 x 148 mm (black anodized aluminum, 27 g) Material: strength aluminum alloy construction with wearresistant surface finish Design goal: Seamless installation on compatible bicycles without adding extra weight Why you need it / how it solves problems Upgrade to Boost: Allows riders to upgrade hubs or wheels to Boost spacing without replacing forks or frame hardware. Interchange wheels between bikes: Makes it easier to swap wheelsets between frames with different spacing standards. Improve wheel performance: Enables wider hub spacing which improves spoke bracing angles and can increase lateral stiffness of the wheel. Typical use scenarios Upgrading a mountain bike wheelset: Fit a Boost hub or wheelset to a fork that uses 15 x 100 mm spacing using the front adapter and included hardware. Swapping wheelsets between bikes: Move Boostready wheels from a Boost bike to a nonBoost frame (or vice versa) where frame/fork and hub endcaps match the conversion dimensions. Building a stiffer wheel: Convert rear spacing to 148 mm to accommodate Boost hub benefits for trail or enduro bikes that accept this conversion. Installation and compatibility notes Engineered for seamless installation on bicycles that accept the stated axle and dropout types; confirm your frame/fork axle standard and dropout fit before installation. Uses aluminum alloy adaptors and supplied hardware to maintain correct axle alignment and secure fit. Designed to resist wear and corrosion while adding minimal weight to the bike. If you need precise fitment guidance, verify your current axle dimensions (15 x 100 mm front, 12 x 142 mm rear) and confirm that your frame and fork are compatible with the listed conversions before installing.
