Figure 4: Heavy gluing of tubular tyres results produces an decrease in rolling resistance. Crr was measured for two tubulars (Vittoria Corsa Crono, Zipp Original) after gluing lightly or heavily. Crr values taken from Al Morrison, AFM_tire_testing_rev9.pdf (http://www.biketechreview.com/tires/rolling-resistance/475-roller-data).
