For a while now I have heard that silica compound tyres are rubbish for indoor velodromes. I have seen a very short list of Manchester approved tubs and tyres, including the tempo and sonderklasse but excluding the conti clinchers and the sprinter and competition. Looking at the conti website, it seems that for their non coloured high end tubs and tyres they are getting away from the asc rubber (activated silica compound) and switching it all to black chili rubber. I see a lot of marketing babble, but no confirmation from conti that they are ditching the silica and going back to regular carbon black rubber.
My questions
is black chili just carbon black rubber?
If so will use of sprinters, competitions, and supersonics be approved on uk indoor velodromes?
For a mix of indoor and outdoor can one be a cheapskate and buy sprinters?
Thanks for any help.
