Hmmm.... well, the crankset was purchased new from RBW within the last year or so. It had been mounted once. I used a torque wrench and did not exceed the maximum torque on written on the crank arm bolts. If the tapers are blown out, it's amazingly easy to do. I'll find out over time I guess (when my pedals start moving funny or something).
I don't know about any changes in machining on the XD2. Perhaps that's the explanation; mine is at least 6 months old, maybe as much as a year old. What's the difference between a triple and a double XD2? Isn't the XD2 QuickBeam sold by RBW just a triple with the outer chainring replaced by a chainguard? I've never seen an XD2 anywhere else; I guess I always assumed it was either some other model re-named for RBW's purposes or simply a specific variety of Sugino crank marketed through RBW. Didn't know there was a triple/double distinction.
