The successor of the Pro 2 Evo - the top seller even more optimized.
The Pro 4 hubs got a reworked hub body with bigger flanges to follow the trend to bigger wheels. With higher flanges you'll get a stronger and stiffer wheel compared to the Pro 2 Evo.
The new rear hub also gets a bigger ratchet mechanism with now 44 teeth for 10% faster engagement over the Pro 2 Evo.
The hub is available with different types of freehub body.
The reworked Shimano 11-speed freehub body now offers enough space for any Shimano and compatible 11-speed cassette. A Spacer for 9/10-speed is included in delivery.
Of course every Pro 4 can be easily converted to other axle mounts, all Pro 2 Evo conversion kits are compatible with the Pro 4 hub.
High-quality and preciously designed rear hub made of 2014 T6 aluminium. 135 mm bolt in version.
The Pro 4 hub includes a further development of Hope's proven ratchet mechanism. It features a one piece 7075 aluminium rotor body and pawl carrier. Four pawls engage into a 44 teeth steel ratchet fixed into the hub shell, sealed with a frictionless, non contact labyrinth seal. The compatibility to different frames and forks is enabled with the help of several conversion kits. Increased spoke flange diameters spread the spoke holes away from each other to allow the use of shorter spokes to build a more durable, stiffer and stronger wheel. They all run on stainless steel bearings now which results in a greater lifespan, smoother, free running characteristics and even more value for the money. With the bearing change comes a new axle. The 17 mm axle version brings total compatibility with Maxle and Maxle Lite thru-axle systems for rear wheels. Compatible with all brake discs with ISO 6 hole design.
The Bolt-In version offers a stiffer connection of the rear wheel and the frame than traditional quick releases. The 10 mm allen bolts are included in delivery and allow for the hub to be installed in frames with standard 10 mm dropouts.
