Innovation AND Technology

Disc Only

Disc Only

Disc specific design allowed for aerodynamic optimization of the frame and fork and a wheel/tire choice that would not have been possible with rim brakes.

KNØT SystemBar

KNØT SystemBar

Provides the low drag and sleek look of a one-piece system, with the fit and Interchangeability benefits of a two-piece bar and stem. 8 degrees of pitch adjustment.

HollowGram KNØT 64 Carbon Wheels

HollowGram KNØT 64 Carbon Wheels

Combining cutting edge aerodynamic tech patented by HED with all of the benefits of big tires, the KNØT 64s are one of the absolute fastest wheelsets in the world.

Hidden Cable Routing

Hidden Cable Routing

Unique design routes brake lines and Di2 cables through an opening in the front of the headtube, bypassing headset bearings. An integrated steering stop prevents damage to the cables and permits a full +/- 50 degrees of steering rotation (regular riding rarely sees more than 35 degrees of movement).

Gated Spacers

Gated Spacers

Stem spacers open so that you can adjust stem height without needing to pull cables.

Power 2 Max

Power 2 Max

We’ve partnered with Power2Max to offer their ready-to-activate NG Eco Power Meter Systems on select 2019 models.
