Pro5 Hooked Flange Boost XD Rear Hub

Hope Pro5 Hooked Flange Boost XD Rear Hub is a precision-built rear hub for modern Boost-spaced mountain bikes, pairing Hope durability with a flange interface engineered specifically for Berd spokes while running a XD driver for SRAM-compatible cassettes.

Built around a redesigned, hooked flange geometry developed under official Berd license and validated through joint testing, this hub targets consistent spoke seating and repeatable wheel builds—especially important when working with Berd’s unique spoke interface.

Key details that matter on the trail and in the wheel stand

1. Berd-approved hooked flange interface - Flange spacing, angle, and seat profile are designed for secure Berd spoke fit, consistent tension, and long-term durability in demanding wheel builds
2. CNC-machined 2014-T6 aluminum shell - Strong, precise hubshell construction for reliable alignment and hard-use longevity
3. Stainless sealed cartridge bearings - Smooth rotation with weather-resistant sealing for reduced service frequency in wet and dusty conditions
4. Center Lock rotor compatibility only - Clean, fast rotor installation for Center Lock brake setups
5. Pro5-level sealing and bearing quality - Uses the same seals, bearings, and build quality found across the Hope Pro5 hub platform
