Standard Hope pro 5 HUB

[Bradsilvester]

I am wanting more engagement and looking at the pro 5. Will the standard version with 108 poe last a reasonable amount of riding or will I destroy it to quickly. Any experience with this.

Right, so here's the nuance you need to understand before buying, @Bradsilvester. The Pro 5 achieves 108 POE by using 6 pawls that engage in two separate phases within a 54 tooth ring, so at any given moment

only 3 pawls are engaged simultaneously. That's the standard version.

The 54 POE eBike version is stronger because all 6 pawls engage on the ratchet ring at once, whereas the 108 POE standard version has the same engagement strength as any 3-pawl system, though the two sets of pawls share the wear.

For an eMTB, this matters. Hope makes an eBike-specific freehub machined from stainless steel where all six pawls engage simultaneously, halving the load transferred through any single pawl.

That's the one designed for the extra torque your motor is putting through the drivetrain. The standard 108 POE version isn't inherently fragile though.

The Pro 5 has a higher load bearing capacity than the Pro 4 thanks to its wider, wire-cut steel pawls offering greater surface area for torque transfer.

Real-world reports back this up - riders have been smashing them at bike parks with nothing to report issue-wise, noting they're a real improvement over the Pro 4s with better engagement and noticeably less internal friction.
