I was wondering if anyone here has experience with these tires on their tandem. I have asked Santa for a set and don't know if I want the 26x1.5 or 1.75 on our Burley Rock N Roll. We do mostly club type road rides, 2-4 hours. Team weight is 290lb. Rims are Velocity Aeroheat. Currently running Serfas Seca 26x1.25. Any input is greatly appreciated.
