Cervelo doesn’t embrace new technology just because it’s available and popular. Integrating disc brakes into the Tour de France-winning R3 meant a lot more than simply slapping them on. First, the technology had to be on track for UCI approval — the R3 is a renowned road-racing force, after all. Then they repeatedly tested to ensure the optimal balance in aerodynamics, weight, stiffness and all the other factors that separate Cervelo from the competition. The result is an R3 proven pedigree with disc-brake technology that has improved stiffness, handling, safety, and control.
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are some benefits of electronic shifting that you don't want to miss.
Electronic shifting systems use powerful servo motors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with surgical precision and without chain rub.
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you'll never have to replace a derailleur cable ever again.
