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 an bigger ratchet mechanism with now 44 teeth for 10% faster engagement over the Pro 2 Evo.
The reworked Shimano freehub body options now offers enough space for any Shimano and compatible 11-speed cassette.
The hub is available with different types of freehub body.
Important note: Hope freehub bodies are only compatible to Hope cassettes. For using Shimano or SRAM (XD) cassettes you need to select the corresponding option.
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. Version for thru-axle with 148mm over locknut distance (Boost).
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.
Note: The hub is delivered without thru-axle.
