Specialized S-Works Turbo 2BR 2Bliss Ready T2/ T5 Black 700c x 28 Tyre Pair in Black with Silca v2 Sealant

When tubeless performance on race day is mandatory but durability for rough roads all season is just as important the Specialized S-Works 2BR delivers - from cobbled classics to your daily lunch ride. The all-new Gripton T2 compound is the fastest most efficient compound they've ever created. They've combined this with the legendary grip of the Gripton T5 compound on the shoulders to the turbo 2BR more grip speed and durability than ever before - six watts faster vs the previous 2br and just 260 grams for a 26mm tyre.

As a tubeless tyre, the new turbo 2BR can self-seal punctures when used with rapidair sealant that is if a puncture can ever pierce the blackbelt protection under the tread which delivers 8% more puncture protection than the previous tyre. This new blackbelt was created using hybrid-kevlar protection under the tread. You've not only got improved puncture protection but lighter weight and more flexibility for a more supple ride.

The new S-Works turbo 2BR is also compatible with both hooked and hookless rims for the flexibility to ride the wheels and pressure you want. The new zylon-reinforced beads also exceed hookless burst pressure standards by 200% for ultimate peace of mind. When it's all about efficiency and great handling in concert with incredible durability you'll see the S-Works turbo 2BR performing everywhere from the world tour to local training rides.

Ultimate sealant has been two-and-a-half years in the making and achieves market leading sealing performance, with longevity and easy maintenance. It's capable of sealing holes up to 6+mm, while its hybrid natural and synthetic latex formula makes it long lasting and injectable, allowing clean top-up.

Silca's sealant has long made use of fiberfoam® technology, which contains small strand carbon fibres, 400% stiffer than fibreglass, to plug punctures quickly and with minimal air loss.

The new formula ensures it will dry less rapidly and stay liquid for up to 6+ months, while adjustments to the carbon strand length have facilitated injectability, without any sacrifice of sealing power. The formula is also safe with co2, not losing its effectiveness or coagulating during the inflation process.

The fibre dam created by the carbon fibre gives fast, effective sealing with minimal air loss, even in extreme conditions, such as temperatures down to -15°c, ensuring this sealant won't let you down.

Shop mechanics, meanwhile, will benefit from reduced labour time for installation and enhanced customer satisfaction, due to the sealant's ability to be injected through the valve core for easy replenishment.

Finally, Ultimate sealant is not only non-toxic and more environmentally friendly than competitors, but kind to your tyres, as it contains none of the ammonia that can break them down over time.
