Important! An update has been made to the Pro 5 Trials S/S free hub. The free hub for the Trials S/S hub now uses 4 pawls, not 6. Please click here for more information!
IMPORTANT UPDATE: Hope Technology have announced they are suspending the Bronze colour option until January 2025. This is due to concerns about quality control, and colour consistency. Hope strive to produce the best finish possible on all their products, and they feel there are improvements that can be made to the Bronze finish for a more consistent colour across their range of parts. All special order for parts in Bronze colour are suspended until further notice, but the colour will return in January! We apologise for any inconvenience caused.
- New pawl and ratchet mechanism with 108 engagement points!
- Zero drag free hub labyrinth seal
- Larger diameter free hub end bearing for improved wear life!
- The new Pro 5 Trials S/S rear hub from Hope has been redesigned from the ground up, offering some significant upgrades over the legendary Pro 4!
-
Please note, all options where an axle type is not stated are 135 x 10mm bolt in.
- New update free hub with 108 point engagement utilises a 4 pawl offset design where 2 pawls are engaged at any time on the 54 tooth ratchet ring.
- A redesigned spring and pawl greatly reduce rotational friction. Material removed from the centre of the spring reduces spring force and free hub drag.
- Wider pawls now sit inside the spring, which acts as a pawl seat inside the free hub. This helps increase load capacity and reduce wear of the free hub body pawl seats.
- New drive side labyrinth seal has zero drag and improved sealing against water and dirt ingress. It's also now much easier to remove and install the seals and free hub!
- Main axle has been machined with increased distance between the free hub bearings to improve stiffness. A taper on the drive side allows for a larger diameter drive side bearing for increased strength and durability.
- A new 2014 grade T6 alloy hub shell increases stiffness with sleek, new, laser etched Pro 5 graphics!
- Tough aluminium alloy axle has M10 threads in the end to accept large bolts (included in the price), featuring an 8mm allen key fitting to improve bolt head longevity and ensure your wheel stays put! The 12mm version differs slightly, having a plain 12mm hole through the hub for use with 12mm bolt through rear axles / frames only.
- Suitable for 135mm and 142m spaced frames.
Please note: for frames with 135 x 12mm spacing you may need to switch the 3mm free hub spacer supplied for a 1.5mm spacer for the cassette lockring to clear the frame. If you need a spacer please get in touch!
- Steel 6-speed free hub body resists digging in when used with steel sprockets.
- Runs on a full compliment of new, custom made stainless steel sealed cartridge bearings.
- 6 bolt International Standard disc mount for those electing to run a rear disc.
- Stocked in a wide range of colours, drillings and axle styles. If there is a variation not listed that you would like to order, please contact us.
- Tough alloy axle provides a solid basis for the hub, and allows the hub to be held in place with heavy duty M10 stainless steel axle bolts with serrated washers.
- Includes a Hope single speed spacer kit (but not the lockring).
- Weight: Standard version: 470.5g including supplied axle bolts. 12mm through-axle version: 369.0g

- LH (non drive side) Flange Diameter: 57mm
