I recently got caught in the rain so when I got home, I took my chain off (SRAM with gold Powerlink) and cleaned it to the point where it was all shiny again. After lubing it with White Lightning and letting it absorb, I took my bike out for a ride (next day). I noticed that when I was shifting through the gears (9 sp. 12-25 cassette) that on the larger cogs (20 & up), I feel something grinding or a soft clicking noise while pedaling. It doesn't happen when I'm in a lower cog, just the higher cogs. Is it possible that I re-attached the chain the opposite way due to not paying attention to which side I took the Powerlink off of? Or could this be a sign of chain wear?
