Matt, BQ studies tire construction to determine which designs give the rider the fastest and most comfortable ride quality. It is alleged that the speed percentages measured in the BQ studies (like the slowest tire tested was ~20% slower than the fastest tire tested., iirc) adds up over long distances. So a 10 hour ride with the slowest tires, in theory, would take only 8 hours on the fastest tires.
I have not noticed significant speed increases with GB or Compass tires over others I have ridden. But they are very comfortable, seem to keep their momentum up very well when starting up a hill, and their cornering is fantastic. I didn't get the last two benefits from my Schwalbe Marathons, though they were also excellent tires. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
