Ack triathletes. Can’t hold their line, a complete disaster in a group. Keep them out of your pace line, or they will cause a crash with their aero bars.
Disclosure: I am a time trial specialist, so I do have a time trial bike. I do not ride it in pace lines, well, maybe in a group training for a team time trial.
