[Tested] Peaty’s Products – Valves & Sealant

Peaty’s Products has been innovating and releasing handy new goods, backed by the legend himself; Steve Peat, winner of 17 World Cup DH races. We’ve been curious about the brand since Steve Peat announced the launch, and got our hands on some tubeless products to test out. Read on for more details.

Specs – Valve Stems

  • 42mm (tested) & 60mm lengths
  • 11 Color Options
  • Integrated valve core remover
  • Applicable for valve holes up to 8mm diameter
  • Lifetime repair or replace warranty
  • $32 USD Retail


We opted for the all black color-way, though as these valves are made in conjunction with Chris King, they can also be found in an array of anodized colors. We were impressed with the attention given to even the most minute detail. The valve cap / core removal tool works very well, and fits snugly in the hand. The larger than average lock ring that keeps the valve in place is easier to thread tight due to its surface area. To cap things off, the Peaty’s tubeless valves are backed by an impressive warranty that states: “If you manage to break, snap, bend or crack our valves then we’ll fix or replace them free of charge!”.

Specs – Tubeless Sealant

  • Manufactured in the UK
  • Ammonia-free, Non-hazardous, Latex-based
  • Filling guide printed on bottle
  • BioGlitter fills larger holes
  • $30 USD Retail

We were huge fans of the easy fill lines printed on the side of the bottle. No measuring cups required, simply empty straight into the tire. Included for reference on the back of the bottle is recommended usage amounts based on tire size. The bottle is re-sealable for storage.

Perhaps the most notable feature of Peaty’s tubeless sealant is the incorporated ” BioGlitter ‘, a” special form of cellulose from hardwoods, primarily eucalyptus sourced from responsibly managed and certified plantations operating to PEFC ™ standards. Peaty’s rationale behind incorporating the glitter is that it “works like platelets in your blood, building up behind holes to help our fast acting sealant form an even stronger bond with the rubber in your tire”.

A closer look at the ‘BioGlitter’, it sure makes your tire look more shiny! Too bad it’s hidden inside for only you to know about. Below is a video of our attempt to puncture a 2mm hole in our tire in an attempt to watch the glitter do its magic.

As advertised, the BioGlitter quickly stops up the flow of air when the tire is punctured. We lost only a few PSI in the time it took to create a hole, and to spin the wheel to distribute the sealant around the inside of the tire. The ease of use when it comes to filling a tire with sealant, and the functionality of the BioGlitter has us pretty well convinced. Precision machined valve stems with an included tool, a plethora of color options, and reasonable price, make Peaty’s Products a top choice for setup of with your tubeless tires.
