It hits all cogs that it shifts to in the center of each cog, meaning the brifter is set to 8speed spacing. It only hits seven cogs though. I can eliminate the small or the large but it just won't get all eight. The stop screws are not the problem. Since I can get it to the big gear but it won't hold because there's no click, I'm thinking there's just more crap to be cleaned. The parts are metal, not plastic so I'm hoping to save it. Frankly brifters are new to me and I don't want to take it apart. The video looked real easy but I was eying the spring and washer the mechanic had sitting on his bench with some consternation. I've pulled apart flat bar shifters and could never get the spring back in place and the cover back on. I'm much more comfortable in the C&V section. DON'T JUDGE ME.🤓
