M10 X 1.25 Pitch Male Thread with 1" Ball

Great way to mount stuff to the bars. I used a pair to mount some mirrors. Works great! I added a little blue loctite to the threads to avoid them easily backing out. Only thing I would like to see is a way to get a wrench on these to tighten/loosen them.

Write I ride fairly fast in all kinds of terrain and wanted a mirror I could see clearly out of and that is what I got. This mirror mounts solidly to my Sportsman 570 and gives me a clear view all the time. No shake or rattle. It is also fairly easy to move out of your way with a large wing nut to loosen the adjustment points I can rotate it out of the way when I need to lean forward on a steep hill climbs in the mountains and then quickly get it back into adjustment. My only complaint (and this is pretty minor to me) is I over tightened one of the clamp bolts and snapped it off when installing it. I didn't think I was putting that much pressure on it at the time. I just got a new bolt and didn't tighten it so hard the next time. Over all I would definitely spend the extra money on this mirror for the clear view and solid mounting. It also looks pretty good. your review here.
