The model 65 also known as the Criterium, is made using the same tubing as the 64. At the ends, its O.D. is 24.2mm and its wall thickness is 1.7mm. The thickness will vary between the ends based on bends and bulges in the bar. The 65 uses a 100mm long sleeve to build its outer diameter up to the 26.4mm diameter used in a Cinelli stem. The centermost 40mm of the sleeve is knurled for the stem to grip. One of the chief differences between the 65 and the other two Cinelli bars we sell, is the short length of the top section which is just 165mm (6 1/2") long, before each side sweeps into its forward curve. The front face of the forward curve has a groove to recess the brake and shift cables should an aerodynamic brake/shift levers be used. The 65 has a 144mm drop, with the lower flat section being approximately 4.25" long. The 65 is Clear anodized leaving the bar a Silver color and is available in three widths 40 cm, 42 cm, or 44cm. The weight of the 42 cm width Criterium is 313 grams. Made in Italy.
