I am having some troubles fine tuning my Avid Ultimates once I changed rear rotor to 140mm G3. It seems I need to either place some shims under the rotor - or some washers between the rear caliper mount and frame. I am using the front 160 adapter mounted backwards in the rear, and is seems aligned fine, but at the edge of its range. It was easy to adjust with 160 G2 it came with on the same frame/hub/caliper...
What is a better place to shim in this case - under rotor, or under caliper mount to bring it closer to the rotor? What is the common wisdom? I have never had to do that previously... I wonder if I did something else wrong, of if the adapter that was in the bag is somehow a wrong once (I mounted fron on posts...) Not too many options..
