Hello,
My Pros Pro Challenger II has a linear gripper and I have noticed that recently it is pinching the string to the point where it is obviously damaging the string and I have had a couple of racquets where it breaks within a short play - typically if the pinched string ends up on a return. It is worse the higher the tension and unlike other models there doesnt appear to be any ability to control the limits of the gripper. It appears worse on Babolat RPM Blast although other stiffer strings appear less effected.
The pinch appears to be closer to the back of the gripper and initially I thought it might be dirt and have heavily cleaned the jaws with goo gone and then isopropyl alcohol but having retested it is still just as bad.
Is there anything I could do? The limit of travel appears to simply when the jaws can touch the tension bar drum so there is in theory no limit to the gripper. I was maybe thinking of adding some offcuts of other string to 'share' the load maybe.

These are a few photos of the gripper and the impact it has on the string, for this one I did pull at much tension as I could on the machine so around 65-70lbs but you can clearly see the indentation, it doesnt look like it slips as there are clear gripping marks. It also appears to only really effect the last couple of centimetres the most. I dont think that the jaws are not closing in a nice parallel manner, I do see some bolts to be able to disassemble but I am really worried about the springs and ball bearings disappearing and I make the situation worse than it already is!
Thanks
