New from Crewkerz, the WAW Ultimate free hub, available in disc and non disc versions!
- Trials specific hub with 108 engagement points!
- Ideal upgrade for Crewkerz Jealousy and Ozonys Curve riders!
- Available in 135 x 12mm axle only.
- With the increasing success of rear free hubs in top level competition, Crewkerz have released their own free hub designed specifically for trials!
- Available in 135mm spacing only, in a disc or non-disc variation to suit both 20" and 26" bikes.
- The Crewkerz free hub uses 4 pawls with two teeth each, which engage on a 54 tooth ratchet ring. The pawls engage in pairs, helping to evenly distribute load on the mechanism, and increase the effective engagements for a single crank revolution.
- Free hub gives 108 engagement points for a complete rotation based on 4 pawls engaging in groups of two on the 54 tooth ratchet ring. With an 18:12 gear ratio, this equals 162 engagement points for a single crank rotation. For an 18:15 gear ratio, this equals 129.6 engagement points for a single crank rotation.
- Each pawl uses a lightweight spring to help reduce rolling friction. A curved pawl design, pointing upwards towards the ratchet ring, helps the pawls engage quickly, and cleanly under load, helping to prevent skipping.
- A total of 5 sealed cartridge bearings (3 in the free hub and two in the main hub body) keep things rolling smoothly, and help to distribute load on the axle, reducing load stress.
- A solid free hub seal with rubber skirt helps to keep dirt and moisture out of the drive mechanism.
- Both versions of the hub are supplied with a sprocket lock ring that uses a Shimano Hollowtech II tool fitment.
- Hub body is machined from 7000 series aluminium, and finished in a stylish satin silver colour, with laser etched WAW Ultimate graphics.
- Both version of the hub are 135mm x 12mm axle standard only (to fit Crewkerz / Ozonys). Axles are sold separately
here.
- Both versions of the hub are 32H only.
- Rear disc hub is 6-bolt ISO standard.
- Both versions available in silver colour only.
