Had friends recommend these tyre warmers in the PCRA (Post Classic Racing Association) as there aren't too many to chose from in the way of 18 inch tyre warmers these days. At first I thought they are a little expensive as I can see cheap Chinese ones online, but then having researched the brand, came to the conclusion that Capit are clearly the choice of many of the top teams in different road racing championships around the world. So they must be good? So I purchased a set and have to say they work great. Only wished I ordered a custom set in a colour that matched my bike, as opposed to just ordering the black colour. Thanks Capit 5 Stars.
