Installed the velo-orange units last night - one set up super easy, the other I had to fuss with a bit more to get the pad to lock down.
It's sort of a double lock-nut situation with the inner threaded post plus the 8mm nut at the pad. I could get the pad angle to lock, but the pad itself wanted to spin on the post.
I finally did get it (it really didn't take that long) but I was apprehensive it might loosen up in today's race but it held.
Is there an order in which the pieces should be adjusted?
Also, I took the used pads out of the TRP units and put them in the VO pad holders and saved the new shoes. One comment - the set screw on the VO units is one allen key size smaller - I swapped the TRP screws onto the VO pads so the F&R would be the same (kept the stock TRP pads on the rear).
