SD COMPONENTS SD-X EVO AIR REAR HUB
The SD-X Sniper Evo Air rear hub is designed for young riders seeking maximum efficiency and instant power transfer. This full engagement rear hub combines a lightweight construction in aluminum with SKF ABEC-5 bearings, delivering high-level performance for BMX racing.
Thanks to its advanced direct engagement system, the hub reacts instantly to every pedal stroke, minimizing delay and enabling explosive starts. The system operates completely silently and generates no resistance during freewheel.
The hub is supplied in a 10 mm version with titanium bolts and can be converted to a 15mm thru-axle Air hub using the Evo Rear Hub conversion kit available as an option.
Customize your hub with interchangeable components available in a wide range of colors.
NOTE : For maximum performance, optimal reliability, and extended service life, SD strongly recommends the use of original SD-X specified wheel bearings.
