I puchased a used CoMo tandem. The right barrel adjuster was frozen. Attempting to free it, I broke it off. Photo of left adjuster attached. It's aluminum in a steel frame, so the right one was corroded in place.
1) What brand are these/where can I get another one? Or another pair with the same threads?
2) How can I get the broken threaded part of the right one out? I broke off a 1/8" easy-out in it already, after soaking with WD-40. I did manage to remove the easy-out chunk, but it wasn't easy.
Looks like someone didn't believe in anti-seize.
