While recently washing the bike after ~50+ days of straight rain and daily commuting, I noticed what appears to be some odd chain wear patterns on the back of my rear sprocket (ie. side opposite the swing-arm). Does this seem normal? The chain is within proper specs in terms of adjustments, and is the OEM chain. I have 13,000 km's on the bike.
Pic 1. This is the easily visible side of the sprocket (ie. the swing-arm side)
Pic 2. This is the back side of the rear sprocket (looking through the rear wheel). What I am concerned with are the shiny silver wear marks along each tooth... (highlighted in yellow, the area is visible on the other teeth)
PS - please ignore the dirt on the inside of the swing-arm; it's gone now, but it had been a LONG time since the bikes last wash, and with all the rain I was applying chain lube almost daily to prevent rusting...
