bearing gifts

My custom-spec Giant TCR Advanced SL Disc was the basis for the ceramic upgrades. My original bike weighed

7.866 kg( see spec below) and the chassis was 5.03kg (frame/fork, drivetrain, pedals, two bottle cages, saddle, stem and bar). The front wheel was 1.26kg and the rear 1.53kg.

After the upgrades the chassis was downto 4.92kg (same as above), with the front wheel 1.23kg, and rear wheel

1.51 kg. Even though the over sized pulley wheels meant more chain links, the overall saving in weight was 206g, that’s not an insignificant amount but weight isn’t really the primary concern when switching up to ceramic bearings.
