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. The freewheel toothing now has 44 teeth and thus 10% more locking points than the predecessor model. This results in a free travel of just 8.2 ° when entering.
The freewheel body has been completely revised and now comes with two, instead of three, camps. To ensure durability, these are sized larger.
Well-known features such as the various anodized colors, the sealed stainless steel bearings and the replaceable freewheels were retained. Also the weight has remained.
The Boost version has a wider hub body than the 135/142 mm version. With her, the flanges are moved by 3 mm to the outside, which optimizes the angle of spoke to rim and thus allows significantly stiffer wheels, which results in a significant performance, especially in 29 "wheels.
