I’ve been on a 2015 supersix Evo ultegra since, well…2015! I love it, the geometry, the ride, the look. I’ve changed a few components over the years, wheels, stem, bars. I’d never get rid of it.
I’m less fond of the new version but only because it looks like every other bike out there now and has lost its classic look, oh, and the livery is terrible. I’m sure the ride is beautiful though.
I’ve done countlesss long days on it including lots of gran fondos Inc a 7 day haute route and 3 Maratonas.
Pf30 Bottom bracket was great until I tried to replace it myself. Last year I got a wheels manufacturing ceramic BB installed and its been first class. No seat post or other issues.
