In my experience, the SKS P-50 is a better match for 650b tires. I've use them with everything from Col de la Vie's to Hetres and Fatty Rumkins and they've worked fine...

Pending further input, I'm leaning towards the conclusion that P45s simply don't work very well with 41mm tires. However, I'll make a call up to RBW later this morning for their input. The warp was noticeable right out of the box, with a 15-20 degree twist. Even with the greatest clearance I obtained on my front fenders, the warp still rubbed my tire.
