Hard Enduro has a single obsession: grip at walking speed over horrible terrain. This guide turns deep technical research into a practical, pick‑your‑setup article that helps you ride better, spend smarter, and avoid DNFs.
Quick Summary
- Need 100% flat‑proof for racing/remote? Use mousse (soft rear if you want more conformity). Expect higher cost and periodic re‑lube/replacement.
- Want maximum traction tuning and best long‑term value? Use Tubliss. Run 3–8 PSI rear in gnarly terrain, bump pressure for fast sections. Plug punctures trailside.
- Want simplicity and low PSI without going full mousse/Tubliss? Consider Lucioli 7mm tube with dual rim locks. Run ~4–6 PSI rear, high durability.
- Ultimate protection? Tubliss + worn “half‑mousse” hybrid for bead security, bladder protection, and a run‑flat safety net.
Why traction in Hard Enduro is different
To hook up on wet roots, slick rock and sharp ledges, you must run very low PSI so the carcass wraps obstacles. That creates the Stability Paradox: low PSI = huge grip at crawl speeds, but sketchy at high speed (the tire starts doing the suspension’s job). Your system choice determines how low you can go, how safe it is when punctured, and whether you can quickly adapt PSI for faster sections.
Your options (from simple to pro)
1) Standard/HD/UHD tubes (baseline)
- Cheap and available, but pinch‑flat prone when run low; UHD can feel springy and is harder to mount.
- Best for easier terrain or casual riding where rocks/roots are limited.
2) Advanced low‑pressure tube: Lucioli 7mm
- 7 mm thick walls plus two in‑mold rim locks massively improve low‑PSI viability.
- Typical HE pressures: rear 4–6 PSI, front 5–8 PSI.
- Reported durability up to ~300 hours. Requires widening/chamfering rim holes during install.
3) Tubliss (tubeless conversion)
- A 100 PSI inner bladder acts as a 360° rim lock and rim protector; the main tire cavity becomes true tubeless.
- Outer tire PSI is tunable down to ~3 PSI for max conformity, or bumped up for stability on fast sections.
- Trail punctures are often fixed in under 2 minutes with a plug kit.
- Long lifespan across many tire changes; excellent TCO.
Tubliss vs. tubeless: what's the difference?
- Tubliss is a branded dual‑pressure system. The 100 PSI inner bladder clamps the bead all the way around, so you can run very low outer PSI without burping, and it cushions the rim on sharp hits. The outer chamber is tubeless, so plugs work quickly.
- Standard tubeless (no bladder) relies on an airtight rim bed (factory TL rim or taped conversion) and the tire bead alone. At very low PSI common in hard enduro, beads can burp/unseat and rims ding more easily, so pressures are usually kept higher (often 12–16+ PSI), reducing crawl‑speed traction.
- Hard enduro usage: Standard tubeless is uncommon. Most riders choose mousse (100% flat‑proof) or Tubliss (low‑PSI tunability + easy plugs). Trials rears are a special case and run true tubeless.
4) Mousse (foam insert)
- Flat‑proof by design. The gold standard for races and remote expeditions.
- “Pressure” is the foam density feel, typically ~12–16 PSI equivalent; softer rears improve conformity.
- Cons: heat‑sensitive at speed, 30–60 hour lifespan typical, needs lube and is harder to mount; highest TCO.
5) Hybrid: Tubliss + spent (“half”) mousse
- Tubliss keeps 360° bead lock and rim protection; a worn mousse inside the tire adds internal armor and run‑flat capability if the carcass is cut.
- Excellent for extremely rocky zones or riders prioritizing redundancy.
Head‑to‑head: What actually matters
| Feature | Mousse | Tubliss | Lucioli 7mm | Standard/HD/UHD |
|---|---|---|---|---|
| Flat resistance | 100% flat‑proof | Very high; sidewall cuts can end ride | High at low PSI | Low–Medium |
| PSI adjustability | Fixed by foam density | Excellent (3–15+ PSI) | Low‑PSI capable | Limited by pinch risk |
| High‑speed feel | Can get vague/overheat | Stable if PSI bumped | Good for intended PSI | OK at higher PSI |
| Lifespan | 30–60 hrs typical | Hundreds of hrs (unit) | ~300 hrs reported | Varies |
| Install/maintenance | Hard, needs lube | Medium; easy tire swaps | Medium; rim mods | Easy–Medium |
| Long‑term cost (TCO) | High | Low | Low–Medium | Low |
Setup cheat sheet (starting points)
- Tubliss: rear 3–8 PSI, front 5–10 PSI depending on terrain and speed. Add PSI for prologue/fast transfers.
- Lucioli 7mm: rear 4–6 PSI, front 5–8 PSI for technical terrain.
- Mousse: pick compound for desired “feel”; softer rear for tech, standard for mixed. Monitor heat on fast sections and re‑lube per maker.
Always adapt to tire model, carcass stiffness, rider weight, rim width, temperature, and speed. Re‑check pressures hot vs. cold.
Chooser: pick by rider profile and terrain
- Racing or remote where a flat is unacceptable → Mousse.
- Mixed terrain, value, and max tunability → Tubliss.
- Simple upgrade with true low PSI on a tube → Lucioli 7mm.
- Extreme rock + redundancy → Tubliss + half‑mousse hybrid.
Buying and maintenance checklist
- Match tire carcass to system (very soft rears shine with Tubliss and soft mousse).
- For Tubliss, keep the inner bladder at 100 PSI and carry a quality plug kit and mini pump.
- For mousse, stock approved lubricant, set a replacement interval (30–60 hrs typical), and avoid prolonged high‑speed heat.
- For Lucioli, widen/chamfer rim holes per instructions; check the two rim locks regularly.
FAQs
Is Tubliss reliable for racing?
Yes—if installed correctly and PSI is set for speed. Many riders race on Tubliss; carry plugs and mind high‑speed pressures.
Can I run Tubliss with a mousse?
Yes. The hybrid uses Tubliss for bead security and a worn mousse as internal armor for run‑flat redundancy.
How often should I re‑lube mousses?
Follow the brand, but checking at each tire change and before long high‑speed days is a good baseline.
What’s the cheapest way to get real low‑PSI grip?
The Lucioli 7mm tube: low PSI with strong rim locking and long life, without mousse complexity.
