"2011 Boxxer Gets Tweaked"
The Boxxer gets a retuned Mission Control DH damper and new adjuster knobs, plus a new, lighter and stiffer Maxle Lite DH through-axle. The top-end World Cup model also gets a new Solo Air spring design. We're introducing a new tuning package to the Mission Control DH [damper] based off some work we've done with the BlackBox riders. Basically we’ve changed the rebound piston to reduce the amount of compression force that it’s generating, which allows us to re-valve the compression assembly in such a way that each of the clicks has more resolution, so each click makes more of a difference and gives much more of a grounded feel with the front wheel.
For the World Cup model ($1,700), the Solo Air spring has undergone two design changes that should have a major impact on the fork’s performance. It features a new air equalisation design that uses a Schrader valve instead of a conventional port system, and the Solo Air spring assembly has been moved further down the fork leg to reduce stiction.
The old Solo Air assembly travelled past the lower crown into the upper tube under full compression and if torque specifications weren’t precisely followed, the tube could actually catch the air piston assembly. The new piston assembly doesn’t enter this space under full compression, so the fork should not suffer from friction or stiction in the latter part of its stroke.
Friction is further reduced by replacing the main seal O-ring with a quad ring and Delrin backers rings. As well as making the fork more slippery, this should also prove more durable.
A Schrader valve, instead of a solid piston, is now used to swap air from the positive to negative chamber. This is said to give the fork a more solid feel. As the fork tops out, the Schrader valve is depressed and the air flows.

Boxxer’s new Solo Air spring and Schrader valve
The Mission Control DH adjuster for the 2011 Boxxer, pictured left, is refined for easier adjustment
Boxxer’s new bottom-out volume adjuster knob
The new Boxxer rebound assembly features larger return flow ports and a refined shim stack for better deep stroke recovery
From the outside, Boxxer looks unchanged for 2011
