Building on
One of the key design objectives for the Pro 5 hub was the reduction of drag in the drive mechanism. This has real world riding benefits and was achieved by upgrading the sealing with a new zero drag labyrinth seal, and an improved ratchet and pawl system, with new springs. Both greatly reduce drag as well as increase durability and load capacity when compared with the Pro 4.
Another big update on the rear hubs comes in an increase in the points of engagement (from 44 to 108) using an offset 6 pawl freehub design, where 3 pawls are engaged at any time. This achieves the right balance between speed of pick-up, load capacity, drag & durability, and in real-world terms gives a speedy feel on the trail whilst keeping crank movement to an acceptable level without compromising the free running of the hub or its reliability.
The extra torque and weight of E-bikes has greatly increased the demands on all drivetrain components, hubs being no exception. The Pro 5 is now offered with a freehub specially tailored for E-Bikes. All six pawls engage simultaneously. Reducing engagement but greatly increasing load capacity and durability. The freehub is fully machined from stainless steel for greater strength and wear resistance.
Externally the shell takes a new profile to add stiffness without adding weight whilst housing a new axle design enabling the use of bigger bearings in a better arrangement to fit the latest freehub standards whilst increasing load capacity.
