All-round wheelset for disc brakes

As an all-rounder in the new DURA-ACE wheel line-up, the C50 is lighter than the previous C40 model and almost as aerodynamic as the earlier C60. This balance bike feels at home in a wide variety of conditions. Whether time trial or criteria, hilly terrain or the attack on your own personal best time, the new C50 is the ideal balance bike for ambitious racing cyclists.

The brand new DURA-ACE C50 wheels convince with the optimal combination of low weight and aerodynamic performance, with the revised full carbon tubeless rims in particular offering high rigidity and reduced weight.

Highlights

  • All-round tubeless wheels made of lightweight materials with balanced aerodynamics
  • 50mm high full carbon rim
  • Modern exterior width of 28mm
  • Direct engagement

Technologies used

In this chapter we explain the technologies that the manufacturer uses for this product.

Centerlock
The centerlock system of the brake disc with multi-tooth profile and locking ring makes assembly easier. This system of assembly using a locking ring enables quick assembly and disassembly of the brake disc and thus saves service costs. In addition, the secure fit on the multi-tooth profile ensures greater precision and strength, which increases the effectiveness of the brake.

OPTBAL
The OPTBAL HR spoke system uses 21 spokes: 14 on the right and 7 on the left. The cassette width in today's wheels causes unbalanced tension in conventional 1: 1 spoke systems. This imbalance is intensified by the 11-speed cassette, which exerts almost double the tension on the spokes on the right. Under certain circumstances, high and low tension spokes can break or loosen. An unbalanced tension affects the lifespan and strength. The OPTBAL construction balances the spoke tension and thereby improves the wheel stiffness as well as the strength for a more robust wheel.
