With the Pro 4 Hope heralds the latest evolution of its hub. The already well-known for their quality workmanship and indestructibility hub was further to stiffness and durability, improved ways.
So it has a larger flange diameter than its predecessor and still allows thus stiffer wheels. The freewheel gear now has 44 teeth, or 10% more locking points than the previous model. This results in a free travel of just 8.2 ° when accelerating.
Even the freewheel body has been completely redesigned and now comes with two, rather than three, bearings made. In order to ensure the durability of these larger dimensions.
Known features like the multiple colors available, the sealed stainless steel bearings and interchangeable freewheels have been retained. Also the weight has remained.
The Boost version has a wider hub body than 135/142 mm variant. For her, the flanges are moved by 3 mm to the outside, which optimizes the angle of the spoke to the rim, thus enabling significantly stiffer wheels, resulting in a significant performance gain especially in 29 "wheels.
