Jolly Codge is being WAAYYY too diplomatic about these crappers. They were a PITA and extreme time-wasters to set up, AND they worked poorly. There was no such thing as "dialed-in", LOL.
A shop I worked at got a coupla sets as a "sample" from one of the importers. We tried to get them to work decently, but none of us were impressed with the end results.
The much better performance of even a cheapo Shimano RSX lever put these things to shame.
Forget any pretense of using these as shifters, and they do make for a stylish stand-alone BRAKE lever. Style over substance, thats for sure.
