Vectran (TM) Breaker Vectran is a synthetically manufactured high-tech fibre from a natural model. Like spider silk, Vectran is a liquid-crystalline polymer (LCP). Vectran is spun from melted liquid polymer Vectra and processed further to a multi-strand thread. Spider silk, like Vectran, has an enormous tear resistance at a very low weight - exactly the right properties to process into a premium Continental bike tyre as a puncture protection insert. A Vectran Breaker is lighter, more flexible and protects more effectively against cuts than the comparable nylon breaker. Vectran Breaker does not adversely affect the rolling resistance. Black Chili Compound Continental refine newly developed synthetic rubbers with natural rubber with the proven high-performance tread compound. They use these rubbers with special nanometric carbon soot particles, which are optimized in shape and surface properties for best uses for the intended tyre. Black Chili Compound reaches an unprecedented of performance. Tyres with Black Chili Compound reach an unprecedented level of performance. Compared to the previous best Activated Silica Compound, Black Chili tyres have 26% less rolling resistance, a 30 % higher friction value (grip) and a 5 % increase in mileage.

This deal was originally found at Evans Cycles website, a bike shop which can trace it's roots back nearly 100 years! Evans Cycles is a London based chain of cycle shops, complete with an extensive online shop. Founded in 1921 by Frederick Evans in Kennington Road, SE London, the business traded for 30 years before being acquired by Joseph Smith in the 1950s, selling a range of cycles and toys. By the 1970s, focus was diverted solely to bicycles and cycling related equipment, and in the following years several franchised shops were opened. These were later brought back under the control of the main Evans company in the 1990s, at which point the famous Evans mail order catalogue was launched, complete with the traditional green and yellow colour scheme. With the growth of the internet, a website was launched in 1999 to help increase sales further, the latest incarnation of which can be found at www.evanscycles.com.
Since the early 2000s' the company has been steadily expanding, regularly opening new stores each year. By 2012, Evans employs 1100 members of staff, and currently has over 50 stores in the UK, making it one of the biggest cycle retailers in the country. In addition to selling a wide range of popular brands, Evans has also produced product ranges under "Pinnacle" and also currently has an exclusive deal with the "Hoy" brand.
