It is true that even in an equivalent gear that a derailleur system has more drag than a single gear setup because of imperfect chainline and the drag of the derailleur pulleys, but I sincerely doubt that just this drag is significant enough to manifest itself as fatigue over a 50 mile ride that otherwise wouldn't happen. Have you given the bleriot a thorough check to make sure that nothing's dragging on the wheels, and that the wheel and bottom bracket bearings are spinning smoothly?
Also, what pressure are you running the Paselas and Hetres at? On May 20, 3:13 pm, Tyler <[email protected]> wrote: > I've had my bleriot for 2 years and my quickbeam for 1 year.
