Tri bikes can be very dangerous if people ride in a paceline while in the aero position. There is a lack of control issue and a lack of brakes issue. When riding a tri bike in the horns they are safe depending on the riders skill. The rider has to move to the end of their aero bars to shift, but I personally don't feel this is any more dangerous than using a down tube shifter. It is much safer in my opinion than getting a drink from a water bottle while riding.

Locally, we have ONE unstable triathlete who wobbles like a son of a ***** whenever he shifts gears. Since the cycling club has had so many wrecks, they are trying to find ways to avoid potential problems. Instead of going to this one rider and saying, "Hey, you are unstable, don't ride your tri bike here until you gain more skills," they decided to outright ban tri bikes.

The person who is responsible for this ban had a wreck WHILE ON A ROAD BIKE AFTER THE BAN was put in place. It goes to prove that the problem is the cyclist, not the bike.
