Freddered, my riding has been restricted over the last month as I've been away. However, I am pleased with the avids so far (no flex, no screech, quality rim-friendly blocks, smooth operation and easy to fix). Without changing levers and cables they have already improved braking. nevertheless, in my opinion this has been only a relatively small improvement and is certainly disproportionate to the cost, but could still be important and significant in an emergency situation. I think with rim brakes, something less than half the efficiency is down to the hardware and the rest is the set-up and maintenance. I don't regret buying the avids as they offer simple excellence and are supremely fit for purpose, which is the principal I am looking for in my bike build.
