Following three years of development, Peaty’s has released a brand new tubeless sealant formula, and we can attest that it is a big improvement over the previous version.
The Holeshot Biofibre Tubeless Sealant is a water-based latex solution that is ammonia-free and is claimed to last up to six months inside the tyre. Compared to the old stuff it has a notably lower viscosity, which makes it more mobile inside the tyre casing and easier to get through valve cores. The biggest change however is the addition of microscopic biodegradable cellulose fibres, which are said to boost sealing capacity by helping the latex to matt together and form a tighter bond.
Peaty’s is still using biodegradable glitter inside the sealant, though it’s been changed from blue to black to make it a little less conspicuous. These bioglitter platelets are a big part of the solution’s sealing capacity, working with the biofibres to plug up larger holes. According to Peaty’s, the new liquid tyre goo will seal punctures up to 6mm.
So far our experience has been very positive, with the Holeshot Biofibre sealant being significantly easier to work with than the previous formula, which was much thicker. You’ll still need to make sure that you give the bottle a good shake to get all of those fibres and platelets properly distributed, but the new solution does a better job of coating the inside of the tyre, helping to minimise sidewall seepage while also sealing holes quicker.
