Viathlon R.1 - 2021, 54 cm

The 2021 Viathon R.1 is a high-performance carbon road machine that offers a professional-grade riding experience at an incredible value. Built around an ultra-lightweight 870g carbon frame (size 54), this build prioritizes raw speed and climbing efficiency, weighing in at a nimble 15.8 lbs. It is equipped with a flagship Shimano Dura-Ace 2x11 drivetrain for the smoothest mechanical shifting available, and has been upgraded with premium HED Vanquish 4 carbon wheels and a full Zipp carbon cockpit. With only 100 miles on the odometer, this $6,900 MSRP build is in pristine condition—professionally tuned and 100% ready to lead the group on your next fast-paced road loop or weekend century.

Why We Love It

 * Pure Performance Build: Between the sub-900g frame and the full Dura-Ace groupset, the R.1 is a "no-compromise" climber that feels explosive when you stand up to sprint or tackle steep gradients.

 * HED Carbon Advantage: The HED Vanquish 4 wheels are a major upgrade, providing elite-level aerodynamics and stability in crosswinds while maintaining a lightweight profile for acceleration.

 * Pro-Level Cockpit: Outfitted with Zipp SL70 Ergo carbon bars and a Zipp carbon seatpost, the bike offers superior vibration dampening and a clean, high-end aesthetic.

 * Understated Stealth: The R.1’s minimalist graphics and matte finish give it a sleek, stealthy look that hides its world-class performance capabilities from the competition.
