I am in the process of replacing the bushing and pivots on my 2011 Element MSL. I noticed some heavy pitting along the rear chain stay pivot meets the bottom bracket. See pics below.
It could possibly be wear from dirt and debris build up getting sandwiched between the chain stay and the bottom bracket. There seems to very space between them. The bike has been well cared for but has seem many days of poor riding conditions.
Is this normal wear in this area? Should I be concerned?
