RockShox has officially launched their latest Boxxer fork featuring all-new internals, 38mm stanchions and other spicy tech to cushion the gnar.

The new Boxxer is available in two models and two colours. Run it stock at 200mm travel or fit a new air spring and run it at 180mm or 190mm on an Enduro or eMTB.

The development crew at Rockshox say they ran extensive testing on stanchion diameter and wall thickness to achieve optimal ride characteristics. “We could have made the stiffest fork possible, but we didn’t. We set out to deliver the best possible balance between stiffness, compliance, and comfort for maximum control. Two years of extensive development focusing on the critical blend of bending and torsional stiffness ratios resulted in the all-new 38mm BoXXer chassis.” – RockShox.

The stanchion wall thickness and lower leg architecture is tuned to be stiff enough to accept steering input, without beating up the pilot’s hands.

Internally, a new DebonAir+ twin tube air spring is unlike any other they’ve released and they are saying it delivers infinite adjustability, with a coil-like feel. “At the top of the travel, we boosted the negative air chamber volume to better absorb small bumps. At the bottom of the stroke, a new bottom-out bumper gives you soft, clank-free landings off the biggest drops. No matter if you’re cornering, careening through rocks, or on a choppy straightaway, BoXXer finds traction where you never thought to look.

New oil flow ports on the stanchions (top left) flush lubricant onto the bushings and maintain air volume for a supple ride on the small bumps and a consistent feel on the big hits. Flat or drop crowns are available, which will allow riders to get the exact setup they like. Incidentally, this also improves compatibility with eMTB riders who are interested in fitting a triple crown fork to their lap machine.

Minimum rotor size is 200mm.

Also included in the new Boxxer are the massively successful rubber pucks, known as Buttercups. As is the case on the Pike, Lyrik and Zeb forks, these small inserts are positioned inside the lower fork legs and reduce the quantity of high-frequency vibrations transmitted to the rider.

Setup is simplified with the new and fully independent LSC and HSC circuits.

The new Boxxer also gets the Charger 3 damping unit that runs independent high-speed and low-speed compression circuits, allowing riders to fine tune their setup without cross-talking between the two compression circuits. 15 clicks of low speed compression, 5 clicks of high speed compression and 18 clicks of rebound are on offer.

Since early 2022 and under the brand’s BlackBox development program, pre-production units of the new fork have been spotted on the World Cup circuit and at freeride competitions like Darkfest. Chat to your dealer for local availability and pricing. More: sram.com
