Precision-machined disc brake hub for 6-bolt rotors (44 mm bolt circle) — built for stable rotor mounting, long life, and consistent performance. Key benefits - Stable braking interface: High-precision cutting produces accurate, repeatable surfaces for a secure six-bolt, 44 mm rotor fit. Reduced rotor runout and more reliable braking feel. - Durable and wear-resistant: CNC-integrated machining plus a high-quality aluminum alloy body increases wear resistance and extends service life. - Lightweight but strong: High-density construction with impact resistance prevents deformation or rust while keeping weight low. - Reliable engagement and drivetrain performance: Three-tooth, five-claw driver design improves power transfer and overall hub responsiveness. - Easy wheel changes: Quick-release design provides fast installation and removal (manufacturer lists a 120 dB specification for this model). Features and specifications - Rotor mount: Standard six-bolt, 44 mm bolt circle — compatible with common six-bolt disc rotors. - Driver design: Three-tooth, five-claw configuration for consistent engagement. - Spoke pattern: 32-hole high-density flange for balanced spoke distribution and wheel strength. - Manufacturing: CNC-integrated processing for dimensional accuracy and wear resistance. - Material and finish: High-quality aluminum alloy construction with anodized surface for improved corrosion protection and a refined appearance. - Durability: Impact-resistant and lightweight design to maintain strength without deformation or rust. How this solves common problems - Eliminates rotor wobble and inconsistent braking by providing a precise, repeatable mounting surface. - Reduces maintenance and replacement frequency through wear-resistant materials and machining. - Improves ride feel and power transfer with a positive driver engagement design. - Makes wheel swaps faster and more convenient with the quick-release system. Practical use scenarios - Mountain trail riding: Built to resist impacts and wear on rough singletrack, delivering stable braking and reliable hub engagement on sustained descents and technical sections. - Road and gravel riding: Compatible with six-bolt rotors and designed to offer precise rotor alignment and lightweight durability for long group rides or mixed-surface events. - Commuting and bike upgrades: A practical upgrade for daily riders who want a tougher, longer-lasting hub with easier wheel removal and consistent braking performance. What to check before purchase - Confirm your rotor is a six-bolt type with a 44 mm bolt circle. - Ensure your wheel build uses a 32-hole rim and that quick-release axle compatibility matches your frame or fork. This mountain bike disc brake hub combines precision machining, a durable anodized aluminum body, a three-tooth five-claw driver, and a 32-hole, CNC-processed flange to deliver stable braking, improved performance, and long-term reliability.
