  • [ Aerodynamic Adjustable Seat (AAS) ]
    DARE aerodynamics model series’ seat post integrates adjustable seat clamp with 73 to 77 degrees of variable seat tube angle. In addition to the angle of 74 degrees supported by general road bike with respect to comfort geometry, an angle of 77 degrees may also be adjusted for time trial geometry to provide the best explosive power for sprint in typical triathlon competition. Moreover, Di2 battery holder is integrated into seat post, such that all Di2 cables are combined inside the frame to keep concise appearance of the bike body.
  • [ Integrated Hidden Seatclamp (IHS) ]
    IHS is a seatclamp merged integrally with top tube. Other than the effects of hydromechanics, the compact top tube is shaped as a blade to provide a stunning visual impact.
  • [ Hidden DM Rear Brake (HRB) ]
    DARE also considers rear brake in its aerodynamics integration design by covering Direct Mount brake on the bottom of bottom bracket to minimize air resistance. Combining HRB design with direct pulling brake internal routing, DRAE provides the most efficient direct braking.
  • [ Transformer Stem Bar (TSB) ]
    TSB integrates a stem-handle bar system to provide various extended lengths and angles for use. Based on the UCI 3:1 regulation, more adjustment spaces are provided for the integrated system used by TSR, such that riders could configure the best riding posture with respect to ergonomics without feeling uncomfortable during a long-term race.
  • [ Total Synchro-Integrated Cable (TSIC) ]
    TSIC is an innovatively integrated internal routing system that conceals the derailleur cable and brake within the frame completely. In addition to perfect compact profile, turbulent flow and interference from cables for time trials are both configured to minimize air resistance.
  • [ Rotating Angle Controller (RAC) ]
    RAC is a hidden stem steering limiter that guarantees riders to keep the bike forward. When in race, RAC prevents handle bar from colliding with the top tube due to the deflection of the bike head.
