S3 Thoroughbred Meets Workhorse
The world championship-winning S3 is back — and even better than before. Combine proven S Series aero performance with the cutting-edge stiffness and lightweight design that comes from our Project California research facility, and you get what Ride Magazine has called “quite possibly The Perfect Bike.” The S3 is ready to put the hurt on a “friendly” Saturday morning ride, or just get you to the coffee shop a little faster. Stiffer, better-riding, aero as ever. All with zero weight penalty.
The S3 aero road bike teams category-leading stiffness and ride quality with an award-winning aero frame, with key features like Future-Proof Cable Routing and Partial Seat-tube Cutout.
This asymmetrical 79mm bottom-bracket standard yields stiffer and lighter frames and crank systems.
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.
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.
Future-Proof Cable Management
Ensures your frame is compatible with all current and future derailleur and brake systems.
Partial Seat Tube Cutout
A close-fitting curve in the seat-tube’s trailing edge improves aerodynamics by partially shielding the leading edge and top of the rear wheel.
Reduced-Friction BB Guide
Significantly reduces cable friction in the bottom bracket, which means smoother shifting, easier setup and longer service intervals.
