The Hope Spiderless Retainer Ring Boost is designed specifically for their new cranks and uses a narrow/wide design to grip onto the chain and stop it from dismounting when riding over harsh and uneven terrain, which theoretically means you can ditch your chain guide for this simple and clean looking system. It mounts directly to the crank's axle and does away with the need of a spider which means you save a whole heap of weight. The Retainer Ring is designed to work with 9,10 and 11 speed set-ups and it provides a quieter drivetrain with less drag. The ring has a 12% ovality and 113 degree clocking, this shape helps you to produce a more efficient pedal stroke by narrowing the diameter of the weakest point and widening the diameter to the strongest point. The CNC machined 7075-T6 aluminium construction provides the perfect blend of light weight and strength whilst the hard anodised finish makes it ultra durable.Designed specifically for Hope chainsetsCNC Machined 7075-T6 AluminiumCompatible with 9spd, 10spd and 11spd Set-Ups12% Ovality113 Degree ClockingHard Anodised FinishApprox.

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 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. The BOOST specific version moves the flanges 5mm further outboard to make an already stiff setup even stiffer, great news for hard-charging riders. Add in 6 different splashes of Hope s signature anodising and you ve got a worthy successor on your hands.
