For those for you worried about using them while we are waiting for replacement stock I can give this advice.
As above I am the original victim of this flaw. What happened was my pads had worn down before a cx race. Had intended to put new pads in but forgot. During the race, which was very muddy, the brake lever became really loose. It still worked but was close to the bars.
When the pads wear get arm pulls so far that the ball bearings are forced out of their mounts. I lost one of the three balls. I was able to strip the caliper and put a new ball in. It works fine an the strip is easy to do.
I think as long as you don’t let the pads get to worn you should be fine to use them until they get the replacements in. It is a great brake. In my opinion better than the BB7. I am sure the redesign will sort the issue.
