Here we have the super duper Evolution line, tubeless ready, G-One Speed tires. (The cheaper Performance line, tube only, versions we used to sell have been discontinued by Schwalbe - drat.) They mount up easy on Atlas,etc. rims and the ride is wonderful. Excellent tires for roadish Hunqapillars, Clem Hs and Ls, Atlanti, and even wider-clearance Bubbes.
Keep in mind that tire width can very a lot depending on the rim you're mounting it on. So far the 700c x 60mm version measures about 2.2" on an Alex DM18 rim and the 650b x 60cm version measure 2.15" on a Velocity Atlas rim.
