CHAIN AND SEAT STAYS
Professional cycling races are long and hard. In recent years, the relationship between rider comfort and increased efficiency has
become more widely recognized in the cycling industry. Colnago has long understood this: the rider who is less fatigued by road
vibration over time is a rider who will maintain maximum levels of performance. This was clearly seen with Colnago’s 5 victories in
6 years in Paris Roubaix, one of the longest and certainly the harshest race on both rider and machine. Colnago’s unwavering commitment
to building the most efficient and comfortable race frames can be seen in the C60’s chainstay design. Similar in design to the C60’s front
triangle, the tubes used for the chain stays are designed with internal ribs, ensuring optimum lateral stiffness. The comfort in the
chainstays is achieved with a tube shape which tapers dramatically towards the dropouts. This provides a slight upward flexion and
offers vertical compliance which actively dampens vibrations from the road. This vertical compliance will also act to increase rear
wheel traction on rough roads.
To ensure more vertical compliance and therefore more rider comfort and less fatigue, the seatstays on the C60 have been designed
to work in perfect harmony with the chainstays. The chainstays have a conical profile with tapered diameter and reduced wall thickness.
The flat and wide tube profile, especially as it nears the rear dropouts, reduces weight while at the same time providing increased lateral
stiffness and vertical compliance.
