6B-Disc Super Boost Rear Hub - 12x157mm

OneUp Components 6B-Disc Super Boost Rear Hub is a purpose-built MTB rear hub for modern 12x157mm Super Boost frames, balancing low weight with the strength riders expect for aggressive trail, enduro, and e-bike use. A simplified internal design reduces part count for easier service, while a 44T star ratchet delivers fast, consistent pickup without adding complexity—an ideal match for riders who want reliable engagement and straightforward maintenance in a high-torque rear wheel build.

• Super Boost 12x157mm spacing - Proper chainline and wheel bracing angle for compatible frames, supporting a stiffer, more stable rear wheel
• 6-bolt disc interface - Direct fit with standard 6-bolt rotors for common MTB brake setups
• 44T star ratchet (8.2° engagement) - Quick engagement for technical climbing and ratcheting through slow-speed moves, with a balance of durability and serviceability
• 7075 aluminum hub shell with integrated drive ring - High-strength shell construction to handle hard impacts and sustained torque while keeping weight in check
• Simplified, low-part-count design - Fewer internal parts to reduce weight, improve reliability, and keep maintenance straightforward
• Tool-free end caps - Faster removal and installation for routine service and wheel swaps
