Our sealant of choice at Bespoke, Peaty's tubeless sealant is an ammonia-free, non-hazardous, latex-based tubeless tyre compound. The sealant lasts up to 6 months in the tyre in temperate climates, won't ball up in the tyre and is easily washed out with water.

The lightweight formula seals quickly and effectively, whilst biodegradable glitter platelets take care of holes and tears up to 6mm. Added corrosion inhibitors prevent degradation of tyres and rims.

The platelets in Peaty's sealant are environmentally friendly BioGlitter - made from a special form of cellulose from hardwoods, primarily eucalyptus sourced from responsibly managed and certified plantations operating to PEFC™ ( standards. They work 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 tyre.

Instructions for Use:

  1. Shake the packaging vigorously before every use to ensure an even distribution of platelets.
  2. Rinse away any old sealant from the tyre and dry off completely.
  3. Seat both sides of your tyre onto the rim and inflate initially with no sealant, using a track pump, inflator or compressor to pop the tyre bead fully onto the rim. If using a track pump, a good tip is to remove the valve core before inflating as doing so allows a greater volume of air into the tyre and so helping it to seat more easily.
  4. Deflate the tyre fully, taking care to keep the tyre bead fully seated on the rim.
  5. Remove the valve core from the valve and put it in a safe place (you'll need to put it back in shortly!)

With the valve at the three o'clock position, push the pouch directly onto the valve to inject the desired amount of sealant directly through the de-cored valve.

  1. Re-insert the valve core and re-inflate the tyre to desired pressure.
  2. Wash away any excess sealant that may have found its way to the outside of the tyre or rim with water.
  3. GO RIDE! This will disperse the sealant around the inside of your tyre and rim, sealing any small gaps.
