I had been using Krylions, but I switched to PR3's, as I figure the PR3's have the HDPP, and thus at much less weight I might be able to give up just a little puncture protection






Grip Compound on the shoulders for maximum grip at unprecedented lean angles

Race Compound in the centre of the tread for maximum durability and minimum rolling resistance

HDPP (High Density Puncture Protection) layer under the tread means, on average one puncture every 6000 Km!
