Improved sealing and reduced drag

Improved sealing helps keep dirt out while reducing drag. The new Labyrinth seal adds zero drag for improved freewheeling performance.

Revised pawls and springs

The revised pawl and spring design increases longevity and load capacity while reducing drag. Wire-cut pawls made from high-strength steel maximise strength. The page lists an offset six-pawl freehub design that increases engagement from 44 to 108, without separately specifying engagement for the e-bike version.

Stiffer axle and hub body

A new step-down axle design provides a stiffer, more durable freehub. The revised hub body profile also increases stiffness without adding weight.

E-bike-specific option

The Pro 5 range includes an e-bike-specific hub designed for the demands of e-bikes. The page does not provide a separate technical specification for this version.

Adaptable fit and straightforward servicing

Support for modern freehub bodies and easily swapped end spacers allows adaptation to different frame and axle standards. The hub is fully serviceable and rebuildable using simple tools.
