Last time we looked at the make up of a Maxxis tyre and the different casings, bead options and TPIs. This week we’ll look at the six different options of puncture protection Maxxis incorporate into their various tyres and which tyres use which.
Silkworm kicks things off with a layer of this exclusive material laid into the tyre casing of certain models. It sits directly below the central tyre tread and works to increase puncture and tear resistance. Silkworm is features in a number of Maxxis’ BMX tyres, entry road tyre (Detonator) and, in conjuction with their K2 technology, in a selection of their road tubular tyres.
Silkshield appears on Maxxis’ high end road tyres, like the Relix and the tubeless ready Padrone and their gravel tyres; the Rambler and Ravager. Essentially the same Silkworm but covers the entire casing from bead to bead, great for sidewall protection against cuts and abrasion. With a protection rating of 3 out of 4, Silkshield provides the same level of protection as Silkworm, but in a lower weight tyre and covers the entire casing.
Another Maxxis exclusive, K2 steps things up from Silkworm. Due to it’s low weight and suppleness, the ride quality and performance remain unchanged when compared to a traditional Kevlar or Vectran tyre. K2 features in addition to Silkworm on Campione and Relix tubular tyres. It is also combined with the Silkshield bead to bead protection layer to create MaxxShield.
And now the pinnacle of road puncture protection. MaxxShield combines the properties of Silkshield with a layer of K2 on top for good measure! If you absolutely hate punctures this is the one to go for. MaxxShield comes on all Maxxis Re-Fuse tyres, creating the ideal winter training tyre or the tyre of choice for those wantng a fit and forget tyre.
For MTB, cyclocross and gravel, Maxxis offers three main technologies to improve the puncture protection of their tyres. These differ from their road tyre protection as they focus more on the sidewalls of the tyre and protecting them against rock cuts and abrasion which is not really an issue for road bikes or hybrids.
Maxxis’ EXO Protection is an extremely cut- and abrasion-resistant material added to the sidewalls of all Maxxis mountain bike tyres. EXO is made up of a densely woven fabric that is lightweight and highly flexible, ensuring that the performance of the tyre remains unaffected. EXO is ideal for rocky, treacherous trails where the chance of sidewall cuts and abrasions is high.
DoubleDown (DD) is the next step in the evolution of the dual-ply tire casing for enduro racing. Two 120 TPI casing layers reinforced with a Butyl insert provide the support and protection of a downhill tire, but in a lighter package which is more suitable for trail and enduro conditions when there isn’t a chairlift to take you to the top!
For punishing downhill conditions, Maxxis add an additional piece of Butyl rubber which extends from the bead up the sidewall of their DH tyres. This extra layer of Butyl helps prevent pinch flats and protects the rim from hard landings which could cause a flat spot in the rim. The Butyl insert also adds stability to the sidewall, allowing lower tyre pressures without the tyre squirming in hard corners.
