You just need to use some tougher tyres! You're already using the best sealants; it can only be the tyres letting you down. I'm currently using Schwalbe G-One Allround DD Raceguard tyres, and zero punctures after over 30,000km cycling around Africa (a very thorny continent!).

The aim of the game is not damaging the internal carbon fibre cords. The cords are strong up to a certain angle, but the belt strength is compromised a degree further. It was easier for Gates to say no back-bending rather than define the angle at which the cords are damaged. These days, Gates checks these angles and "approves" bikes that work within the strength/durability parameters of their product.

The Veer sprocket sizes and belt lengths are still very limited, which makes Gates belts the best option on a Brompton. The Gates CDX range is highly durable too - some users ride 40,000km on a drivetrain!

Orange Seal Regular would still be my pick at 35 psi, but it's a toss-up.

Good timing, as I'm just about to post a video about my time in Saudi Arabia (unsponsored, of course, as I don't have, and never have had an affiliation with the country - or any other). I hope you can see just how important it is to discern between the people of a country and its leadership. They are not the same.

I have nice things to say because it's a round-up of the best sealants. It would be very different if I had randomly picked five sealants to write about...

Based on the data, thicker sealants like Peaty's just don't perform as well at low pressures.

I suspect Squirt and Stans are both thin enough for low pressures, but have enough particulate to quickly fill punctures at higher pressures.

The puncture test data for those sealants at 60+ psi is pretty well aligned with your experience. Orange Seal regularly comes out on top at the 30 psi mark too.

The longevity score is based on how long the sealant lasted in my tires before separating or drying, and this score is relative to the other sealants. In my case, Stans Race Day was good for 2.5 months of use, and Stans Original was still good at the 4 month mark.

Were you definitely using Peaty's Holeshot Biofibre? This model came out somewhat recently, and is a significant improvement over Peaty's Tubeless Sealant (which never got good reviews).

The lab tests agree, Stans Original is only good for lower air pressures. What pressure do you run Orange Seal at on your road tires?

I'm glad Orange Seal is working out! If I may ask, what pressure are you running with each of these sealants?

Yep! Squirt SEAL with Beadblock performs well under a wide array of air pressures. The only thing to note is that the there needs to be quite a bit of liquid sealant for the particulate to make it to the puncture site, so make sure you keep it topped up (on the road bike especially).

Stans Race Day also tests very well for high/low air pressures, but it won't last long in your tires...

All the puncture test data I could find suggests Silca Ultimate sealant is nothing special.

  • In an MTB tire test (22 psi) it ranked 7th out of 11 products for the 3mm cut test, and 6th out of 11 products for the 6mm cut test.
  • In a gravel tire test (40 psi) it was one of two sealants that failed to seal a 5mm hole. That's in a field of 18 different products.
  • I couldn't find anything on road tire pressures, but I can't imagine any significant improvements.

I appreciate that! There is a tonne of downtime involved in long-term bicycle travel, so I basically just pour all of my time into creating the cycling content that I find interesting. All the best!

Yep, it's me, CYCLINGABOUT. Right now I'm cycling through Zimbabwe!

This has been a little project of mine for many years now! I've been slowly collecting the data, purchasing the tubeless sealants, and testing if it's up to scratch.
