HOPE hub rear Pro 4 | Screwdriver Freilauf Shimano SRAM
With the Pro 4, Hope rings the latest evolutionary stage of its hub. The hub, which is already known for its good workmanship and durability, has been further improved in terms of stiffness and durability.
Thus it has a larger flange diameter than its predecessor and thus allows even stiffer wheels. The freewheel toothing now has 44 teeth and thus 10% more detent points than the previous model. This results in an empty path of just 8.2 ° at the start.
The freestanding body has also been completely reworked and now comes with two, instead of three, bearings. In order to ensure the durability they are larger in size.
Known features such as the various anodised colors, the sealed stainless steel bearings and the interchangeable freewheels were maintained. Also the weight has remained.
The Boost version has a wider hub body than the 135/142 mm version. With this, the flanges are moved outwards by 3 mm each, which optimizes the angle from spoke to rim and thus allows significantly stiffer wheels, which results in a significant gain in performance, especially on 29 "wheels.
