well the tires have excellent grip, plus they are very good in the rain, my friend that works at toga bike shop has them, i wanted to get these tires before he told me how good they were. so i took a test ride on his bike, and i felt very secure with them, alot better than those pro race, which i did not like in the rain.
the tire feels good, even at 130 psi they felt good in the turns. they are 315 grams, which would be like a 240 gram reg. clincher tire. 440tpi plus a puncture proof layer and a another protective rubber layer ontop of that. i have been told i could expect 4000 miles on them, i do not know if this is true. one thing that worried me was catching flats on these tires, their goes a $65 tire. but i have gone thru some glass and they are still in good shape. these tires are just made well, period.
if you concerned with weight you can go with elite jet, same build as elite road, but lighter weight 240g (weight is guaranteed) about half the mileage of the ones i have.
if they made a clincher version, i would be all over it. these tires are good, i would encourage anyone to at least try them out. their tubular version is made the same way 240g for elite road, 160 grams for elite jet. i would def, go with a tubular with properties like this: http://www.tufo.com/index.php?lg=en&mn=1&id=46
this is 150 gram version (tri): http://www.tufo.com/index.php?lg=en&mn=2&id=64
