The perfect balance between raw power and all-day ridability, the all-new Synapse combines remarkably light weight, race-proven performance and dialed vertical compliance in a bicycle that redefines "Endurance." The ultimate partner for the epic ride.

An ideal blend of compliance, rigidity, and weight for the perfect balance of race-day aggression and all-day ridability.

Revolutionary. BallisTec Carbon, Power Pyramid and the SAVE PLUS system provide the ideal blend of crush meets plush.

Synapse is:

  • S.E.R.G. Synapse Endurance Race Geometry
    With its slightly taller head tube, slightly longer wheelbase and slightly slacker head angle, S.E.R.G. strikes the ideal balance between pure race positioning and upright comfort. Perfect for long days in the saddle and confident handling on all road surfaces.
  • SAVE PLUS Micro-Suspension System
    The SAVE PLUS Micro-suspension system is a three part system, comprised of the carbon lay-up, the rear triangle and fork, and the seat post and seat tube, all designed to collaborate seamlessly to reduce vibration, improve handling, and increase comfort.
  • SAVE PLUS Micro-suspension system (Rear Triangle and Fork)
    The frame and fork's carbon layup is designed to optimize high-frequency vibration dissipation, reducing road buzz. The radical helixed shapes of the chain stays and seat stays work in conjunction with the offset dropout fork to allow the wheels to track over imperfections in the road for better handling and control, seated or standing.
  • SAVE PLUS Micro-suspension system (Seat post and Seat tube)
    The elegantly scalloped seat tube and the smaller diameter 25.4mm seatpost are designed to flex together to provide more comfort when seated. The integrated collarless seat clamp allows more of the seatpost to flex than with a traditional clamp.
  • Power Pyramid/BB30A
    The seat tube splits asymmetrically to meet a new wider 73mm BB30A bottom bracket, for maximum stiffness with minimal weight.


People who live for the love of the ride. Fit, serious, high-performance riders who set their sights beyond the tightly defined world of the pure racer; Gran Fondo specialists, all-day-epic riders, and those who long to venture off the smooth and easy.

Cycling Plus Votes the Synapse, bike of the year

Synapse BallisTec Carbon frame options:

  • Synapse Hi-MOD:
    BallisTec Hi-MOD carbon construction. High and ultra-high modulus fibers create an interconnected stiffening network throughout an extremely strong and durable base structure. Ultra light, strong and stiff.
  • Synapse Carbon:
    Same lay-up, same molds and same ballistic base fibers as the Hi-MOD version, but utilizing a higher percentage of intermediate modulus fibers to tune stiffness and ride feel.

  • 700 x 28c Tires
    The larger tires (up to 28c) found on the Synapse models provide more comfort, are better suited for differing road conditions, and are less likely to pinch flat.
