Is it crazy to buy a 2021 year model TT bike with rim brakes

I’d go Di2 FAR before the disc brakes if it’s a choice. Major reason on a tri bike is the ability to shift easily and perfectly from the basebar.

Shifting on Ultegra mech is pretty good, and not a reason to go di2. But in the TT config, the ability to use satellite shifters to shift from the basebar with di2 is a significant plus.

My point was shifting from the basebar, NOT the extensions. Out of the saddle climbing and shifting is a no brainer for Di2. If you’re doing any climbing, it’s pretty sweet. Also, there is NO comparison between Mech and Di2 on front chainring shifts, especially under load.
