8. Hex Taper Axle


Hex Taper Axle

The Ellsworth Hex Taper Axle employs hexagonal shaping on both ends to effectively lock the dropouts and hence the seatstay assembly together into one unit that seriously resists torsional deflection. The dropout/axle interface is tapered on both sides for easy axle removal as well as offering the ability to preload the whole assembly to eliminate axial and radial play in the rear end. It is bombproof, lightweight, and easy to use with our tool-free tension system. We’ve built our Hex Taper Axle system to meet the modern 12x148mm Boost standard.
