I have never tried mini-v's on any bike, and I am not a big fan of Tektro products or re-branded tektro products. I lucked out with the Avid shorty 4's and these particular diacomp levers. The lever action is firm, and no squeal. It's a good match.
Also, now with the front cable having some "breathing room", it is not necessary to crank down heavily on the brake springs to make up for the tight cable angle as before... nice and light lever action, vast improvement.
One more hurdle that was overcome, without a barrel adjuster I could not pop the link wire off of the front brake for front wheel removal.... not enough slack. Now, I keep about 3 or 4 mm of threads showing on the barrel, and I can loosen the wire enough to unhook the link instead of fiddling with the pinch bolt, as before.
