This T.J. Quick is 19.3 Pounds as it sits Columbus SLX DA 7700 Nisi 36 hole tubular Rims size 57. The seat post is an early Tom Ritchey Carbon not much lighter than the DA one I have for it. I'm going to do a BB change and a rear Cassette upgrade from Ultegra to DA to see if it will go under 19 Pounds.
