Anyone experience a "tightness" after mounting your camera and making side/side or fore/aft adjustments? My first (2015) M1 rig has tightness in the bearings and now feels bumpy with the fore/aft bearings. Side/side is smooth, but tight. I've never gone to the ends of the adjustments...use my XCS shift plates always.
Second M1 rig...just bought in October...mount a camera and you feel the same tightness...but not any bumpy bearings at the moment.
Of course, with no weight on the bearings...all is smooth.
These are studio rigs and haven't seen any time on a vehicle or the like.
I've replace bearings and races on my U1's...some I'm guessing this is the same issue...
