How could Hope possibly follow on from the legendary Pro 2 It was always going to be a tough act to follow. But with the Pro 4, Hope have seemingly done the impossible. With a ground up redesign, the Pro 4 hub takes everything that made the Pro 2 great and brings it bang up to date. With larger diameter flanges to help increase stiffness on modern 27.5 and 29 inch wheels with no weight increase, the Pro 4 uses Hope s bullet proof sealed stainless steel cartridge bearings that make for an extremely reliable centrepiece to your wheelset. In true Hope style, they sound the business as well!.
