If you’re still running tubes on your gravel or MTB setup, this is the article that might change that. Tubeless sealant is the thing that makes tubeless work — it plugs the small punctures you never even notice and gives you time to deal with the larger ones. The sealant you pick matters more than most riders think. Here’s what I’ve run and what I’d use again.
Quick comparison
| Sealant | Best for | Seal size | Rating |
|---|---|---|---|
| Stan’s NoTubes Race | Best overall, proven formula | Up to 6mm | ⭐⭐⭐⭐⭐ |
| Orange Seal Endurance | Longevity in dry climates | Up to 1/4″ | ⭐⭐⭐⭐⭐ |
| Muc-Off No Puncture Hassle | Larger punctures, aggressive terrain | Up to 6mm | ⭐⭐⭐⭐ |
| Finish Line Tubeless | Budget-friendly option | Up to 4mm | ⭐⭐⭐⭐ |
| Effetto Mariposa Caffélatex | XC and road tubeless | Up to 4mm | ⭐⭐⭐⭐ |
1. Stan’s NoTubes Race
Stan’s invented the tubeless sealant category and their Race formula is still the benchmark everything else gets compared to. It seals small punctures fast, works across a wide temperature range — which matters at altitude in Colorado where you can go from 90 degrees to 40 in the same ride — and it’s available everywhere. The downside is that it dries out faster than some alternatives in hot, dry conditions. Top it up every 2-3 months and you’re fine.
2. Orange Seal Endurance
If you ride in dry conditions — and most Colorado gravel riding qualifies — Orange Seal Endurance stays liquid longer than Stan’s. The formula is designed specifically for low-humidity environments where sealant dries out prematurely. I’ve had it stay active for four months in dry summer conditions where Stan’s would have been a dusty mess. It seals well and the yellow color makes it easy to diagnose where a leak is coming from.
3. Muc-Off No Puncture Hassle
Muc-Off’s formula handles larger punctures better than most sealants at this price. If you’re riding aggressive terrain with sharp rocks — which describes a lot of Colorado trail and gravel riding — the ability to seal a bigger hole before you have to stop and deal with it is worth something. It doesn’t last as long as Orange Seal in dry conditions, but the puncture sealing performance is genuinely good.
4. Finish Line Tubeless
Not the most exciting option on this list but a solid one at the price. Finish Line’s formula works, seals small punctures reliably, and costs less than the alternatives. If you go through a lot of sealant — multiple bikes, frequent top-ups — the price difference adds up. Performance is a step behind Stan’s and Orange Seal but it’s not a dramatic gap for most riders.
5. Effetto Mariposa Caffélatex
A foaming sealant that distributes through the tire differently than liquid formulas. It works well for XC and road tubeless setups where weight matters and punctures tend to be smaller. For rough gravel and MTB use I’d lean toward the other options on this list — the foaming action is less effective on larger holes. But for lighter duty setups it’s a legitimate choice.
How much sealant to use
General rule: 2oz per tire for road and XC, 3-4oz for gravel, 4oz for MTB. In dry climates, err toward the higher end of that range and top up every 2-3 months. If you hear sloshing when you roll your wheel and the tire stays inflated, the sealant is still active. If it’s silent and the tire won’t hold air, it’s time to clean and refill.
My pick
Orange Seal Endurance for Colorado conditions — it simply lasts longer in dry air. Stan’s Race if you’re buying at a local shop and they don’t carry Orange Seal. Muc-Off if you’re riding sharp, rocky terrain and want the best shot at sealing a bigger puncture mid-ride.
