Low Drag Freehub Design 
One of the key design objectives for the Pro 5 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.  

108 Points of Engagement
Another big update 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. 

Improved Hub Shell Stiffness
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. 
 
Longevity
As with every product made at Hope durability and longevity are key. Everything about the Pro 5 has been considered, and tested to work in the worst conditions possible from seals to bearings. Eventually if something does wear out the Pro 5 is fully serviceable and rebuildable with simple tools, or if you need to change drivetrain standards one hub works with everything. So swapping freehubs is easily done, and changing end caps to suit different frame and fork axle standards future proofing your wheels. 

Freehub Body: Choose from SRAM XD, Shimano Microspline, or Shimano HG
