The HD4’s reputation was defined by winning the overall team title in the Enduro World Series. Built for speed, it excels on steep terrain. While slaying the rowdiest descents may be expected of a world class enduro bike, sprinting back to the top is not. Thanks to the dw-link suspension design, cries of “That thing flies uphill” are common among the slack jawed first time riders.

Dropper Post Saddle Height Calculations

Do not try to insert your post deeper than these measurements. Forcing the post can result in a seat tube failure.

IMPORTANT: Before riding, check the saddle to tire clearance with the dropper post fully dropped and the air out of the shock with frame compressed to bottom out.

Saddle height used for dropper measurements:

49mm rails-to-top.
