Introducing the Next Level: MrWolf’s MousseBalls 2.0 Lunar
We’re always looking for gear that gives riders better performance and fewer headaches. That’s why we’re pumped to unveil our latest pre-order: MrWolf’s MousseBalls 2.0 Lunar — a major upgrade in anti-puncture mousse tech that’s nearly ready to ship (ETA: December 2025).
What Are MousseBalls, Again?
For those who haven’t run them yet, MrWolf’s MousseBalls are a modern alternative to traditional mousse inserts or inner tubes. Rather than a solid foam insert (a “bib mousse”), these are modular foam “balls” (segments) that:
- Fill your tire like a mousse but offer more flexibility.
- Let you adjust “hardness” or “feel” by adding or removing balls to suit the terrain or your riding style.
- Reduce operating temperature (thanks to a higher surface-to-volume ratio) by up to 33% compared to standard mousses.
- Be regenerated: the full set includes spare balls so you can refresh sections instead of buying a whole unit.
Slavens Racing already carries the base MousseBalls (front, rear, soft rear, oversize, etc.), so this new Lunar version builds on what riders already trust.
What’s Lunar Bring to the Table?
Lunar takes the MousseBalls concept further with some new features and refinements:
- Self-lubricating compound. Lunar uses a new elastomer material that’s built to reduce friction without requiring you to slather on silicone grease or gels during installation. In short: less mess, faster mount, fewer opportunities for user error or bad lubrication.
- Plug-&-play readiness. Because of that self-lubricating design, Lunar ships ready to run — out of the box — saving time in the shop or trail prep.
- Same modular structure + adjustability. You can still tweak hardness by adding/removing balls. Use all for faster, firmer feel (desert, Rally-Raid fast terrain, etc.), pull some out or leave spacing for softer, more forgiving grip in Enduro, extreme terrain.
- Improved durability, lower vibration. By dropping temperature and reducing vibration (hysteresis), the Lunar version aims to give better control, improved ride feel, less risk of foam breakdown under harsher use.
What to Know Before You Pre-Order
Here are a few important details for Slavens customers (or anyone considering Lunar):
| Feature | Details / Guidance |
|---|---|
| Pre-order timing | Lunar is expected to be in hand December 2025. Place your pre-order so we can reserve your size. |
| Sizing & fit | As always, tire internal volume, carcass stiffness, and rim width matter. Sometimes you may need to add or remove one or two balls to get the “PSI feel” you want. Slavens already lists detailed fitments for standard MousseBalls, which give a good baseline. |
| Return policy | Once installed, MousseBalls (or Lunar) can’t be returned. So double-check your model/size before installing. |
| Feel & break-in | Even though Lunar is self-lubricating, expect a short break-in period. Some early reports on the standard MousseBalls say it takes a ride or two to really settle. |
| Customizing hardness | You can adjust hardness or firmness by how tightly you pack the balls, or by adjusting spacing between them. More tightly = firmer, less spacing = softer “feel.” But leaving too much space may affect how the tire feels and mounts. |
Real-World Impressions
From what users of the standard MousseBalls are saying:
- Riders appreciate the “tube-like” feel—more liveliness than many solid mousse inserts.
- The ability to run mixed terrain (fast, hard, rocky, loose) and tune the firmness is a big benefit.
- Installation is easier than full mousse only in the sense that you deal with segments; but it’s still a bit of work. Lunar will speed the process somewhat via the self-lubrication.
- Durability seems solid: testers with dozens/hundreds of miles report that standard MousseBalls maintain form and firmness fairly well.
Why Lunar Matters for Slavens Racing Riders
At Slavens, we believe in gear that keeps you riding longer, safer, with less fuss. Lunar is a big win if you:
- Hate dealing with messy grease and want to cut down install time. Lunar’s self-lubricating design helps a lot.
- Ride in mixed or unpredictable terrain and want one setup you can tweak rather than buying separate mousses or tubes for different conditions.
- Want the strong anti-flat protection mousse gives, but with more comfort, lower heat buildup, and better ride feel (especially front end feel, which many riders say mousses tend to deaden).
- Tend to put lots of miles in rough terrain—or race—and want something that holds up longer and can be “refreshed” rather than replaced.
If you’re ready, reserve your 2.0 Lunar set now (or reach out if you want help picking the best size or setup for your bike/terrain).
