Yep, with the 650's I'm running 50 pounds. Am tempted to drop that a little, we'll see. With Rubino Pro III's, I usually run 100. Too soo to tell about ride quality, will know more after this weekend. The real reason behind the 650B's was for vintage events with mixed pavement/gravel, like Cino and L'Eroica. I'll probably use the 700's with 25 Rubino's most of the time on pavement.
