Ready for training, this road bike powermeter is equipped with two high-quality carbon crank arms that ensure fantastic stiffness, durability and low weight as you aim to beat your personal performance goals. Quarq has also designed this chassis-only version for compatibility with Shimano Dura-Ace R9100 or Ultegra R8000 chainrings for excellent power delivery and precision on your ride. Thanks to its spider powermeter, this model provides riders with accuracy within 1.5%, measuring both legs for reliable, accurate power analysis. Another highlight is it comes complete with many of Quarq's renowned technologies such as MagicZero, AxCad and OmniCal as well as 10K Temperature Compensation and an IPX7 waterproof rating for reliability and consistency in any weather conditions.
