Make a good fork a great fork. Introducing the Luftkappe air piston kit for Fox Float forks. The Luftkappe is available for: 34 Float NA2 (2016-17) Performance & Factory Series (130mm + only - 120mm and lower need the 2018 Evol air shaft before a Luftkappe can be fitted) 34 Float NA2 Evol (2018+) Performance & Factory Series 36 Float NA2 Evol (2018+) Performance & Factory Series 36 Float NA (2015-17) Performance & Factory Series (max 180mm travel, min 120mm travel) Pinkbike: "The Luftkappe's change to the feel of the Lyrik was immediately noticeable on the trail. Traction was increased across chatter and the fork remained higher in its travel and more stable, improving the dynamic ride height without sacrificing the top end. My confidence soared when hitting sections with a lot of chatter and mid to large-sized hits, and the result meant more comfort and speed through such sections." Taking everything we learned with the Corset air sleeves and the Luftkappe we developed for the Pike, Yari & Lyrik, this second generation Luftkappe is a new air piston assembly for Fox's 34 NA2/Evol and 36 Evol forks. User installable and simple to set up, the Luftkappe transforms a good fork into a great fork. Softer initial stroke Larger negative air chamber Increased sag without the associated diving Coil-like initial & mid-stroke spring rate without excessive bottoming Increased sensitivity Improved mid stroke support & control Superior bump compliance and traction Reduced hand fatigue Reduces required compression damping Retains volume spacer compatibility Optional tools available for self-install What's included in the kit: 34 Evol: Upgrade low friction air piston assembly. 34 NA2: Upgrade low friction air piston assembly & upgrade low friction, low profile sealhead 36 Evol: Upgrade low friction air piston assembly. 36 NA: Upgrade low friction air piston assembly & upgrade topout spacer ring Note: If your 36 Evol tops out noticeably, you will need to replace your air shaft assembly before purchasing the Luftkappe. Fox have updated this part due to the topout issues that many of the 2018 36 Evol forks had. 34 forks do not have this issue. Relevant Fox part numbers for the new air shaft assemblies, by travel: 180mm: 820-02-534-KIT 170mm: 820-02-535-KIT 160mm: 820-02-536-KIT 150mm: 820-02-537-KIT 140mm: 820-02-538-KIT 100mm (36 831): 820-02-539-KIT If your fork does not have noticeable top-out issues, you don't need to replace the shaft before installing the Luftkappe. FAQ: 1. Can I install it myself? Yes, provided you have access to the supplies and tools listed in the installation instructions above. If you're really crafty (and EXTREMELY careful) it is possible to install the Luftkappes (all Evol variants) without the installation tools, however the risk of damaging things is much higher and we really don't recommend trying. If you choose to take this route and damage your air shaft (or anything else), we cannot be held responsible - we make the tools available for a reason. It is not possible to install the 34 NA2 Luftkappe kit without 10mm shaft clamps and the bullet tool - you'll damage the shaft AND damage the seals on the new sealhead. 2. Does it work with TALAS forks? No, sorry. 3. Does it work with versions of the 36 prior to 2015? No, sorry! 4. Does it work with 32s or 40s? No, sorry. 5. How does it actually work? It enlarges the negative air chamber to reduce the initial spring rate. This lets you run higher air pressure for more support in the middle and end of the stroke with improved sensitivity in the start of the stroke. 6. Is it compatible with MRP's Ramp Control cartridge? Generally speaking no. If you are running your fork at least 30mm shorter than its maximum available travel, then yes. 7. Shouldn't I just buy a new fork instead? Sure, they're about the same price as the Luftkappe. 8. What parts does it actually replace in the air spring? It replaces the plastic piston itself, and the rubber topout bumper in the 34s is removed but not replaced (36 topout assembly is unchanged). You reuse your air shaft, though the 34NA2 kit comes with a replacement low friction, low profile sealhead comparable in size to the stock 2018 Evol sealhead. This is also why the NA2 kit is more expensive than the other two - it's basically a 2018 Factory update on top of a Luftkappe. 9. Who is this NOT suited for? The Luftkappe is outright superior to the stock air spring for nearly everyone, however there are a few cases where it might not be for you: - If you run your 36 at 180mm, it will be quite progressive. You may like it, but you may also find it hard to use the last 5-10mm of travel - if this would bother you then have a think about it first. At 170mm and below it will be fine. - If you like running really low sag for some reason. The Luftkappe runs more sag than the stock fork, but is firmer in the mid stroke - similar to a coil fork, but with ending-stroke ramp up to prevent harsh bottoming. If you're the kind of person who wants the fork to run 5% sag, this isn't for you. We could point out that a setup like that probably just means your handlebars are set too low and you're compensating with oversprung suspension, but we aren't here to judge you, so maybe just don't buy it. - If you're anal about your fork having an exact (but rounded-to-the-nearest-10mm) amount of travel. Because the Luftkappe balances forces at a pneumatic topout, the force right around topout is very low (literally zero other than friction), meaning the weight of the bike alone will cause it to sag a few millimetres. Your car's suspension sags under the vehicle's own weight, so should your bike - unless it was so sticky, overly stiff or over-preloaded that 10kg of bike weight wasn't enough to cause your suspension to move at all, of course. If only having an apparent 148mm out of a 150mm fork is a big deal for you, stick with the stock fork.

The new DebonAir+ is built to strike the perfect balance of what riders really want: butter-like small bump feel, increased air volume to add support throughout the travel and higher overall ride height for more confidence when things get steep. This upgrade is for those who have 2023+ ZEB, Lyrik and Pike Select+ or Select models, or pre-2023 model Zeb forks. By focusing on refining the shape of the spring curve, RockShox created an air spring that’s more plush off-the-top, with a supremely supportive mid-stroke and improved end-stroke ramp up. They zeroed in on details to improve small bump absorption to be extremely reactive over every inch of trail and added mid-stroke support allowing the fork to sit higher in travel and utilize every millimeter of travel. The new DebonAir+ offers a supreme ride feel and consistency you can trust. Buttercups Little gold-packaged rubber pucks live at the end of the damper and air spring shafts and fit into the lower leg of the fork. Similar technology is found in off-road vehicles, chainsaws, and most devices that transfer high-frequency vibrations into the hands and arms of the user. Like a rubber mount on the handle of the chainsaw, ButterCups measurably eliminate trail chatter by on average 20%. Proven by data acquisition over thousands of trail miles and confirmed by riders. Featured in all Ultimate models and upgrade-able in the full line up of new Pike, Lyrik, and ZEBs. MPN: 00.4318.085.002

The MRP Noken is a spring upgrade that increases air-spring volume, reducing the compression ratio and creating a more linear spring curve that mimics the plush feel of a coil spring. This simple upgrade addresses a key challenge for many riders with long-travel forks: finding the right balance between a supple initial stroke, strong mid-stroke support, and fully utilizing all the fork's travel. With the Noken, you can optimize that perfect trifecta. Increases the positive spring volume by 1.5 volume spacers on Fox 36 models Compatible with FOX 2018-2025 FOX 36 Factory, Performance Elite, Performance, and Rhythm models, including E-tuned versions. As well as 2019+ Marzocchi Z1 models, Performance Elite, and Performance models, including E-tuned versions Also compatible with Marzocchi Z1 (2019+) models Preserves small-bump compliance and mid-stroke support, while also regaining the travel that is typically lost due to the harsh, steep progression of some stock air springs Creates a more linear spring curve with a less dramatic spring rate change near bottom-out The Noken is 10-13mm taller than standard damper control knobs, so it s important to confirm downtube clearance before installation Installs with a 32mm six-sided socket MPN: WB-24-2223
