2 x Continental Grand Prix 5000S TR 700c Folding Road Tyre in Black/TransparentContinental Grand Prix 5000S Tubeless Ready Tyre - Foldable BlackChili Compound
The new Grand Prix 5000 S Tubeless Ready: Lighter, faster and with stronger sidewalls. The new standard in road tubeless ready technology. Ride faster, more comfortable and with increased puncture protection. Made to make you better.Features:
- With the previous model already significantly improved in comparison to the old GP4000 S II model (17% in rolling resistance, 25% in puncture resistance), the GP5000S TR raises the bar in the all-around road tyre market to previously unseen levels!
- In the autumn of 2021, the GP5000S TR was the winning tyre at both the men's Paris-Roubaix and World Time Trial Championships, showing its versatility across these very different races with their very different demands on equipment. The GP5000S TR covers them all!!
- Tubeless: The patented carcass construction is robust and impervious against damage from foreign objects. The result: versatility, lower weight and a super-attractive design. With this design, tyres can be used both tubeless or with an innertube.
- BlackChili compound: Nanotechnology used to produce the carbon black particles that are used to reinforce the rubber compound. We refine special synthetic rubbers with natural rubber to create high-performance tread mixtures.

Silca Ultimate Tubeless Sealant 8ozSilca Ultimate Tubeless Sealant combines the power of carbon fibre with a long lasting natural latex formula to achieve sealing properties beyond that of special race day formulas, while matching or exceeding the life expectancy of long-lasting formulas.
The key is a high percentage fill of recycled, chopped carbon fibre strands which are held in suspension by the foaming action of the sealant within the tire. Upon puncture, the sealant rushes to escape the hole, carrying thousands of carbon filaments which serve to dam up the opening, just like sticks of a beaver dam blocking a stream. This dam of fibre collects more fibre and what was one large hole, is now turned into hundreds of smaller holes for the sealant to seal.
Fiberfoam technology has proven to seal up to 7.5mm holes and cuts at gravel pressures and up to 5mm holes at higher road pressures. Even better, the carbon fibre/latex plug formed at the puncture has proven to be more than twice as strong over time as latex only or latex with crystals or glitter.
While most sealants claim they can plug holes up to 6+mm, they can also be injected into the tyre through the 3mm hole in your valve stem with some injectors using tips as small as 2mm. The power of carbon fibre makes this impossible, Silca Ultimate Tubeless Sealant will instantly plug your injection syringe or your valve as the fibres stack up to block the opening. In solving this issue, the Silca team has developed Ultimate Tubeless Sealant into a system that will save you time and money in the long run.
The initial installation of Silca Ultimate Tubeless Sealant must be done by pouring into the tyre cavity rather than injecting through the valve. However, unlike other sealants which must be completely replaced every 3-6 months, Silca Ultimate Tubeless Sealant has a special Replenisher which can be pumped through the valve and can extend the sealant life to well over 1 year depending on your climate. This means less wasted sealant, and less hassle over time as there is no need to remove the old sealant at each service interval, in many cases, the sealant may outlast the tyre.
Please note that CO2 can be used initially to seat tyres, but should be removed as soon as possible and replaced with air in order to maximise the life of the sealant.
