    Ultegra chainring teeth - is this normal?

    chainring..jpg

    Is this normal for an Ultegra chainring with only 160 miles on it? I notice some of the teeth are flattened at the top while others come to a point. Is this due to machining at the factory or is this caused by the chain on the bike? I would not expect to see this after only 160 miles.

    They are made that way.
    The different cuts in the teeth aid in shifting rings.

    Yeah, I looked at some images online and I see they all look like that. Must be the machining at the factory, thanks. By the way Fred did we see you riding Northbound on 518 yesterday at around 6:20PM? Drove past a guy on a yellow bike that looked like you.

    It's rather comical how often this question gets asked.

    I noticed that on a mountain bike I got. I thought someone have been scraping over curbs or rocks.

    Then, I actually bought a replacement, only to find that it was the same.

    I learn a lot off stuff the hard or expensive way.

    yes, but it is hardly surprising. It's one of those things that, if you didn't know the reasoning behind it, it just looks WRONG.

    Nothing like the days when Bio-Pace chainrings were standard on entry level mountain bikes.
    There's always room for one more bike!

    Can we make this a sticky? It gets asked at least once a week.
