Nashbar Prima Plus 2. 27 x 1 1/4". Kevlar, durable "rubber", blackwall. (CST) These roll and handle very well. Have just surpassed 3100 miles and NO wear than I can see. NO flats even though I've picked-out several goat heads, thorns, and a piece of steel or two. They are usually $12.00 each at Nashbar. They replaced a pair of Panaracer Pasella TG's than wore to paper thin at 1600 miles.
