    Cracked Homebrewed Ti cog?

    Anyone else found a crack in theirs? Was flipping the chain ring and cog this morning and installing a new chain when I spotted it. The cog is a one piece 17T Ti, crack runs from the valley of one of the teeth across to the weight relief cut out. Not impressed as this is the first time I have flipped it from new, kind of negates the option of flipping it to double the life.

    Doesn't look good. If this is a defect and not the result of abuse, I hope they'll step up to the plate and take care of it. Already a lot of eyes on them

    How many miles are on that cog and how old is it? It's pretty "hooked".

    I bent my HBC chainring. Not enough to take it off yet. But when I am zoning out on climbs and staring at my drivetrain I get to watch the 'wave' in my chain.

    I would guess at around 900-1000 miles, it was put on new with this chain and front ring in September 2010. My SS gets put away for the winter in October and reappears in late Feb/March so maybe 10 months of actual riding. I was planning on replacing the chain at the beginning of this riding season but never got around to it, the hooking has increased noticeably in the last couple of weeks.

    Looks like a design problem to me. Not a very well engineered lightning pocket IMHO, the tooth flex cracked it at its weakest spot. If the cog had 17 of the small pockets, would have been much better.

    +1 What TacoMan said. Could also have been caused by manufacturing processes.
