I just had a customer come in claiming to have an older bike with XTR and he needs to replace his 34t chainring and said it is 110mm and 4-arm. None of my vendors carry this, do you think he is mistaken or did they really make these? If so where can I find them?

To my knowledge there is no such thing as a 110 BCD 4arm crank, not even as some old weird standard. I'm betting he meant to say 104.

That is what I thought too. He said the 104mm I sold him was too small.

Perhaps the customer was in error and it's one of the older XTR 112/68 cranks (M950, 952)
