I am removing these because I had some muddy rides. I am degreasing and re-packing the bearings with grease.
I was able to remove the upper pully no problem, but I cannot get the lower pulley bolt to budge -- I am assuming it is a regular thread like the upper pully and not reverse threaded?
I tried to put some wd-40 on it to help it break, but have had no luck so far. My main question is whether it is a regular thread or not?
Also, Sram says pack with meduim weight grease? Will a medium weight automotive grease be sufficient? Any suggestions for grease brands?
