I have got some Enve 3.4 SES rims, the front is 35mm and the rear is 45mm deep. They are on Chris King R45 hubs, laced with Sapim CX-Ray spokes. I went for the clincher option as it was right for me, but tubular is available of that's your preference.
They are on the summer bike, so haven't been used since October. They didn't get that much use before having to be packed away for the winter, but they are much more befitting the bike than the previous Alu wheels and I am very happy with them. I plan to set many land speed records as soon as the salt has washed away from the roads round our way and the sun is shining.
