Ritchey Tom Slick 26x1.4 437g

Kenda Kwest 26x1.5 530g

Both are wire bead (the RTS is available in kevlar bead, but it costs much more and I've never tried it). The Kwest costs less and will outlast the RTS at least 2:1 in mileage, also flats less. It's a great value in my experience. Don't pay more for the 100psi version Kwest, it's no better than the normal (65psi) version, just weighs another 70g.
