In '93, I bought a C-dale T1000 for touring. The adjusting bolt (rear?) broke within a month (before trip) and the bike shop replaced it with a nice Syncros. Gary Duke (Dukes Cycle in Toronto) told me this early post was known to have this problem and AC were coming out with a revision, which they did. I was a heavy and hard rider at that time.

I have a later Ti version that I don't ride much and it's been just fine. Data points.
