Born from racing, BoXXer promises one thing above all—composure. By eliminating chaos before it reaches the rider, every run delivers predictable speed, traction, and control. The all-new LinearXL air spring provides a coil-like ride—supple off the top, supportive through the mid-stroke, and backed by a jounce bottom-out bumper for confident end-stroke control—giving you unwavering consistency and predictability. Found only in our Ultimate forks, ButterWagonTech ensures a constant supply of oil to the bushings, reducing friction and maintaining smooth performance throughout the entire service interval. Intuitive HSC/LSC controls on the Charger 3.2 damper with ButterCups technology make setup fast, understandable, and easy to communicate. You’re so composed you don’t realize you’re going faster. But the clock says it all.

Features:

  • NEW LinearXL air spring delivers a consistent and predictable ride feel backed by a jounce bottom-out bumper for end-stroke control
  • NEW ButterWagonTech ensures a constant supply of oil to the bushings, reducing friction and maintaining smooth performance throughout the entire service interval
  • NEW Charger 3.2 damper with new Rebound/Compression tunes that match LinearXL air spring, achieves virtually silent performance, keeping riders focused on the trail
  • NEW Control bezel with numbered Compression adjuster for intuitive adjustments—start at "0" and easily add or decrease damping
  • NEW Graphics package—minimalist design, maximum impact
  • ButterCups technology block 20% of high-frequency “trail chatter” to reduce hand and arm fatigue
  • Low-grab SKF wiper seals deliver long-lasting fork performance and a smoother ride
  • Maxima 920 blended 15w reduces overall fork friction
  • Bolt-on fender compatibility with front and rear coverage (BoXXer Bolt-On Fender sold separately)
  • Available in Electric Red or Ultimate High Gloss Black Signature colourways

Good so far.
Format: Paperback
I will be using these heavily in a month or two, I ordered them because they were on sale so I will come back and edit once I actually read the material, use the glossary, online tools, etc. However from out of the box? All the books are in perfect condition, no sticking pages like other reviews. I will say if you can afford the hardcover version with the labs? Get those. From touching them once or twice so far, this book will not stand up to constant use. It's a really flimsy type.. not even sure if it's paper? It feels like plastic paper. I will also add that that study guide book is F A T . I wish they would have split it into two. I bet the hardcover is gigantic because mine looks like the biggest dictionary you've seen, and I know the cover page which is almost exactly like the pages? Will be ruined once it starts being used consistently.

Very Useful
Format: Paperback
I used these for my A+ exams and I didn’t really end up reading the material. I more so used them for their practice exams. That’s only because there’s a lot of information to digest and I was in a rush to take the exams. I still passed so I find that they are well formatted. The questions imo needs to be read more throughly than the exam questions themselves.
