A dummy hub that stands in for your rear wheel so you can clean the chain, degrease the drivetrain or pack the bike for travel without the wheel in the way. A free-spinning Delrin pulley carries the chain so you can still turn the cranks and shift through the full gear range.

Fit

Built with the double lead-in thread Mavic Speed Release systems use, so it only works on a Mavic Speed Release frame and will not thread into a standard thru-axle dropout.

Compatibility & fit

12mm diameter, Mavic Speed Release double lead-in thread only. Install and remove by hand, no tools needed.
