HOPE PRO 4 BOOST FRONT HUB 

With the Pro 4, Hope heralds the latest evolutionary stage of her hub. The hub, known anyway for its good workmanship and indestructibility, has been further improved in terms of stiffness and durability.

So it has a larger flange diameter than its predecessor and thus allows even stiffer wheels. Well-known features such as the many anodized colors and the sealed stainless steel bearings were retained.

The Boost version has a wider hub body than the QR15 variant. It has 5mm outward flanges, which optimizes the angle from spoke to rim for significantly stiffer wheels, which gives a significant performance gain, especially on 29 "wheels enormously stiff connection of fork and impeller.
