SKU: 73746652 Categories: ,
A modern 24H, straight pull, 6-bolt disc hub featuring our 6D drive system and universal 130mm, 135mm QR or or can be fitted to 142mm thru-axle frames with extra axle kit.

Available with 11 speed Shimano or Campag freehubs.

The ultra-dependable drive system of this hub uses 6 independently sprung, double tipped, reversed pawls; giving 12 point simultaneous engagement on a 30 click cro-mo drive ring.

The uncluttered freehub that a reversed pawl system provides, allows a cartridge bearing to be used directly under the freehub drive ring (rather than an offset position that is commonly used in conventional pawl systems that cram the pawl mechanism into the relatively small diameter of the freehub itself.)

The resultant reduction in offset torque transfer from the freehub reduces leverage effect on the axle and ultimately increases bearing durability.

This results in an extremely positive and reliable drive system.

This universal fitting hub comes supplied as standard to fit 130mm or 135mm QR frames – using conventional 130mm road standard cranksets with a chainline of around 45mm.

This means you can run conventional 130mm ‘road’ chainline cranks and drive train on a 135mm/142mm frame that has short road length chainstays, or of course, on a 130mm frame.   

An optional adaptor (HUHARDRBA5) is available to allow SRAM and other cranks using the wider MTB spaced 135mm chainline of 47.5mm
