Tri-bars…they became popular when I was actively racing triathlons in the late 1980s and early 1990s. There was no more popular way to screw up the balance of a fine Italian racing bike. I recall that they put a lot of extra weight over the front wheel and in front of the stem. I bought a pair back then, used them on no more than two or three training rides and then removed them forever…never raced a Tri with them on my bike.
