Razor sharp chainring? normal for 9spd?(1 post)

Razor sharp chainring? normal for 9spd?DrD
Jul 23, 2001 8:24 AM
I am currently using Ultegra 9spd front rings - they have maybe 5k miles on them - and the teeth are razor sharp - looking from the side, the profile of the chainrings is normal-ish, but feeling the tips, they are all "bladed" - is this the normal wear pattern for the 9spd stuff?

(I broke a DA chain this weekend, and found out how sharp the chainring was the hard way... it's always fun repairing things when you are bleeding like a stuck pig...)
