I could never look at that Kvale enough Grady!
Grady, BBM and the departed OFG all pushed me towards the Veloflex Masters and everything they said was true - it's an excellent, fast tire that rolls quite smoothly. I haven't even had major flatting issues with them. The place I think they really make their mark is performance in slippery conditions - the tread pattern is GRIPPY!
Overall, I think I like the Continental GP4000s SLIGHTLY more, though the Veloflex tires are lighter and roll a bit faster. I like the Continentals for flat protection and gravel/cobble stones a bit more.
