These any good. On offer at min from probikekit.com http://www.probikekit.com/display.php?code=Y1056 Using Spesh Armadillos at present. Looking for something to use on weekend rides in a couple of months when I have my new road bike. I want to do faster weekend rides and the armadillos apparently have appalling rolling resistance and poor cornering. Never noticed but then again I have never used anything else so I guess I wouldn't know what a decent tyre is really like. Will still be using my spesh armadillos for dark commutes as they have never let me down and in the dark it is more important for me to get home puncture free than it is to go faster. Basically I want to do faster weekend rides. I can do 15mph avg at the min (though by the end of the summer last year when I was 4kg lighter and had longer solo rides behind me I avg 16-17mph on 40-60 mile rides over flat terrain) on the flat bar spesh sirrus comp and not riding clipless. I want to bring that average up. Any ideas what I should be aiming for this year on spds, focus cayo full carbon jobbie, with decent tyres and back down to my normal summer weight and if this tyre isn't up to the job what would be best. Must have some level of puncture resistance as really light tyres with no puncture resistance would seem only appropriate to me for time trialling which I have no intentions of getting involved in.
