Leadville Trail 100 MTB

High-altitude MTB hundred — thin air, big climbs, one very long day.

Distance

160 km

Elevation

3,800 m climbing

Discipline

MTB

Character. 100 miles of fast gravel and dirt road at 10,000+ feet, peaking above 12,400. Dry Colorado August conditions most years. Notable for altitude acclimatisation being half the battle.

Conditions. Colorado August: 10–18 °C at altitude, intense sun, dry. Occasional afternoon thunderstorm on the descent. Dust is heavier than European gravel.

Lube plan

If you wax — ZFC-recommended path. 160 km at altitude is long enough to exceed some waxes' SAL. A freshly-waxed chain handles it, but a small oil bottle carried (not automatically applied) is smart insurance. Not a chain-swap event — it's one day, not a stage race.

If you're on oil — pragmatic equivalent. Apply your usual oil the night before; carry a small bottle as insurance. 160 km at altitude on dust-heavy gravel is borderline single-application territory; one mid-ride top-up handles it cleanly if you feel the chain go dry.

Staged recommendation

Ultra-endurance (single continuous push) — staged plan

A continuous ultra (Unbound XL, TCR, long solos) leaves two viable mid-event strategies. Option A: carry a pre-waxed spare chain and swap on course — maximum efficiency, zero post-event reset, ~150 g extra in the kit. Option B: carry a small oil bottle and apply over the wax when the chain goes dry — lighter kit, but you've committed to a chain-stripper degrease at home. Race vs recreational intent decides which. Wax emulsion drips are off the table either way — they need hours to cure that you simply don't have.

No wax emulsion drips mid-ultra. SS Drip, UFO Drip v2 etc. all need hours to set hard — you'll finish before they cure, meaning the top-up does nothing useful. Carry an oil (Synergetic) only.

Critical: Do NOT apply grease or heavy wet oils (Muc-Off Hydrodynamic, WD-40, generic mechanic's oils) to a waxed chain. Those contaminate deeply and create a much harder reset than a clean wet-ride oil like Synergetic.

1
Pre-event (24h+ before)
Wax the primary chain with a top immersive hot-melt
Race mode: wax a second identical chain in the same pot session so you have a spare ready to swap (see Option A below).
2
Event start
Start clean-waxed — ride out the wax for as long as it holds
On a fresh wax, expect 500–1000 km of clean performance on dry road, dropping to 150–300 km in heavy wet or extreme contamination. For a 1000 km+ ultra, assume the wax WILL run out before the finish — plan the mid-event action now.
3
Mid-event — Option A (race / max efficiency): chain swap
Swap to the pre-waxed spare chain on course
~90 seconds with a quick link. Zero post-event degrease — just put the used chain in a pouch, swap in the spare, keep riding. At home: re-wax the used chain like normal, both chains stay in the wax ecosystem. Carry: spare chain + master link / chain tool + rag + a small bag for the old chain (~150 g extra). Best for podium-chasing or efficiency-obsessed riders.
4
Mid-event — Option B (recreational / lighter pack): oil over wax
condition: wax depleted, rain, or sustained wet
Apply an oil over the wax — carry a small dripper bottle
Apply on the move or during a 30-second pause, continue immediately. Silca Synergetic is ZFC's published pick. Carries ~50 g vs ~150 g for Option A, but commits you to a chain-stripper solvent degrease at home (see stage 5). Wax emulsion drips (SS Drip, UFO Drip) are NOT viable mid-ultra — they need hours to cure that you don't have.
5
Post-event (only if Option B was used)
Chain-stripper solvent degrease, then re-wax
Wet-weather oil behaves like factory grease — boiling water and ultrasonic alone will not shift it. Use a proper chain stripper / solvent (mineral spirits, dedicated chain degreaser) with ultrasonic agitation. If you used Option A (chain swap), skip this stage — your used chain just gets re-waxed normally.

▸Portable wax pot for multi-day travel (hotel-based only)— Pack the Silca waxing station rather than a drip bottle — if the trip stays in powered accommodation.
when: Multi-day trips (stage race / training camp) with nightly hotel / apartment stops and car-supported logistics. NOT for tent / bivvy / wild-camp trips — the station is electric and needs mains power.
- The Silca waxing station is a compact mains-powered melt pot — fits in luggage, plugs into a hotel socket. Full melt in ~15 minutes.
- Requires electricity. Won't work at a camping trip (tent, bivvy, van without power) — fall back to the multi-pre-waxed-chains + emergency-oil strategy for those.
- Keeps you on your normal hot-melt workflow end-to-end — no compromise on wear, no drip-bottle decisions.
- Pair with the multi-chain rotation strategy: rotate to a fresh pre-waxed chain daily, re-wax the used ones at the hotel.
Highest-performance travel setup when you're hotel-hopping. Drop back to the drip-top-up / oil-rescue strategies for unpowered trips.

▸Silca Super Secret Drip needs 24 h, not 12— Published set time of overnight / 12 h is optimistic in practice — plan for 24 h.
when: Multi-day scenarios where SSD is a realistic mid-trip top-up option.
- Real-world experience: if you apply SSD after a ride and race next morning, the coat is still tacky. 12 h is not enough; 24 h is closer to the truth.
- In a stage race you typically only have 12–16 h between stages, so you don't get to 'plan' a full set cycle — apply as the chain demands, accept the next morning's coat isn't fully hard, and know a partial top-up still beats running dry through another dusty or damp stage.
- If the scenario genuinely offers a full day of rest between rides (rest day mid-camp, planned weather buffer before a wet ride), wait 24 h rather than the published 12 h before committing the chain to that ride.
- SSD is still the top pot-compatible drip — this is a set-time nuance, not a compatibility one. No other pot-compatible drip has a proven shorter real-world set time; Tru-Tension Tungsten All Weather's 'very short' claim did not replicate in field testing.
Silca Super Secret Drip review (Test 13)·Experienced-user field note (2026-04-24)
▸SAL-only candidates — worth considering for long gravel— Some ZFC-tested waxes (Squirt Hot Wax, Silca Hot Melt + Endurance Chip variants) have exceptional single-application longevity but aren't in the main wear-block league table. On multi-day gravel, that's worth a second look.
when: Any stage-race or ultra-endurance gravel / MTB scenario where single-application longevity matters more than per-km wear differences.
- Squirt Hot Wax leads ZFC's single-application-longevity (SAL) test at 3,783 km real-world on dry road — further than Cyclowax Race Wax (3,033 km) or Silca Synerg-E (3,138 km).
- These lubes sit outside the main Block 1–6 wear league table because ZFC hasn't run them through the full protocol, so they're excluded from the ranked list above.
- For pure distance-per-wax events, an SAL winner can beat a Block-winner in practice — because the Block winner's wax runs out and you lose all its advantage.
- Worth checking the Excluded section at the bottom of the results, or searching ZFC's SAL data directly if you're optimising for longest uninterrupted wax life.

Why this rank
#1 because: dry gravel/MTB/CX riding is dominated by dry-dust contamination — scoring weights 60% on Block 2 (dry contamination) and 40% on Block 1. Cyclowax Race Wax is eligible after scenario filtering and its wear (0.005) is the lowest in the eligible set, which — given your priority weights — edges out every other eligible lube.
