If by some way they arent shifted by payday, i might get back to you. How did you find using them compared to round rings? Any noticeable benefit, or just another cycling fad like biopace etc?
I've found them superb. I've used them for the last three years and wouldn't go back to round rings. For climbing and putting the power down they are great. Not as difficult to set up as some make out, you just have to a half decent mechanic. The shifting quality is fine and only over shoots if you down shift up onto the 53 in teh power phase of your pedal stroke.
