So I've been getting my bike ready for a trip and when I changed the chain I found that it's running rough on the chainring when under load. The bike was built with new drive train in June with ~30-50km per week with 800-1800m of climbing. The chainring shouldn't be worn.
I suspect the square nature of NW teeth means that any wear means that the square teeth foul on the chain rollers as they enter and exit the chainring. Instead of reinstalling the old chain I'm thinking of filing a little chamfer on these square tooth tips. I'm running an oval chain ring and I suspect it's the area of the tight radius on the chainring that is causing the issue. Hopefully that is clearly described, I CBFed drawing a diagram.
Anyone ever try this? I shouldn't cause any issues if I stay close to the tip but if I cause issues I'll have to scramble for a replacement chainring before the end of the week.
