That advertisement is over 5 years old - I'm sure it's been sold by now. smile

But it does raise some questions: Any downside to a crank ground 0.010" undersize? Are the 0.010" oversize bearings prohibitively expensive? And I seem to recall one ground crank cracking because of improper technique (poor radius at the fillets and/or improper nitriding after grinding) - or is that an isolated case?
