Thanks for your response. It really doesn't bother me. A bit surprised to see it however. I generally make sure I have a solid gear change before standing and mashing out of the saddle. Apparently the bend is still within the widith of the window of the chain rollers and links because I didn't notice it last night while riding and I use the 12t cog quite a bit...mostly descents, standing etc.
I will remove that cog and bend it back as you suggest.
Many Thanks for the advice.
PS: Aside from 20 grams, I don't see any material or coating or tooth shape difference between Veloce and Centaur.
I presume the 20 grams diff is spacer material difference or shape. If Centaur is a great value for 10s Ultra drive compared to Chorus, for training maybe Veloce is even a better value and good enough next time.
What do you think?
