Cervélo 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 we needed time to test, test and test again to ensure the optimal balance in aerodynamics, weight, stiffness and all the other factors that separate Cervélo from the competition. Fact is, details matter when changes are made to iconic frames, which is why you can trust us when we say that the R3 Disc is well worth the wait.
This asymmetrical 79mm bottom-bracket standard yields stiffer and lighter frames and crank systems.
Cervelo developed BBright to take advantage of the fact that oversized frame tubes are stiffer and lighter. On the right side, frame tubes are already as wide as possible; any wider and they’d hit the chainrings. But on the left side there are no chainrings, so BBright makes use of this extra space by extending the BB shell by 11 millimetres, nearly doubling the width of the left chainstay.
Future-Proof Cable Management
Ensures your frame is compatible with all current and future derailleur and brake systems.
Future-Proof Cable Management achieves compatibility across mechanical, electronic and hydraulic brake and derailleur systems. Future-Proof frames include interchangeable cable stops that snap into place and are easily swapped out by hand to accommodate upgrades. You can buy with confidence, knowing your bike is easily upgradable and can be enjoyed with the latest technology for years to come.
Tough, compression-molded dropouts save weight with no sacrifice in strength compared to traditional metal dropouts.
Seatstays and chainstays are bonded into hollow dropouts, instead of the other way around. Bonding these precision-moulded surfaces reduces weight, and gives the internal rear derailleur cable a straight shot through the chainstay and dropout, eliminating bends and cable friction.
Evolved Steerer Design
The fork steerer’s diameter has a noticeable effect on a bike’s handling. Evolved Steerer Design applies the diameters and taper designs that best suit each model.
A larger steerer diameter adds torsional stiffness with no weight penalty. A smaller steerer diameter is more compliant and can also be used to reduce headtube frontal area, and in turn, aerodynamic drag. How do we select which size to use? By defining performance goals — weight savings, aerodynamics, stiffness, ride quality and usability — at the start of the frame design process, Cervélo engineers choose the best steerer for each bike.
This library of tube shapes allows Cervelo engineers to “dial in” the weight-saving, aero, stiffness and compliance properties that best suit specific areas of a frame.
Square shapes resist bending the best, while round shapes are tops when it comes to torsion. Since different frame tubes see a variable mix of bending and torsional loads, a careful combination of these shapes can offer the best of both worlds. Enter Squoval, which combines the attributes of a square and an oval to achieve an ideal balance of stiffness, weight and aerodynamics.
