The grumpy old man in me likes my bike to be as mechanical as possible, I don't want to remember to charge my shifters, power meter, gps, etc. Maybe that's why I still ride a 1989 Trek 1200 with down tube shifters and biopace chain rings.
That said I can't vouch for the biopace rings...
(To be read for comedic purposes only. I don't actually ride that one to work.)
