I spent a few minutes on the phone yesterday and gathered some useful tidbits of information, the abridged version:
Pacenti working to release new sizes of their tire line. Other things changing behind the scenes, but all in order to move forward and grow the line!
North-of-the-Boarder" company will soon be receiving some tires (from an undisclosed manufacturer) for 650B testing.
More Big "S" rumors are swirling, but don't ask them directly, you'll get the cold shoulder. They seem to be keeping their lips sealed about 650B development.
