Features

  • 40mm rim depth delivers all-day aerodynamic speed and crosswind stability.
  • CADEX hookless rim technology and refined carbon layup enhance weight savings, durability and tire performance.
  • 22.4mm inner rim width improves sidewall support and creates a more aerodynamic tire interface.
  • CADEX Super Aero carbon spokes reduce lateral flex for more efficient climbing and acceleration.
  • Custom-tuned Dynamic Balanced Lacing (DBL) increases spoke bracing angle and optimizes static and dynamic spoke tension for greater lateral stiffness and maximum power transfer.
  • Traditional spoke and hub design for increased serviceability.
  • CADEX R3-C48 Aero hub with 48-tooth ratchet provides fast engagement and responsive power.
  • CADEX Ratchet Wave Spring ensures smooth, consistent hub operation under load.
  • CADEX ceramic bearings minimize rolling resistance for maximum efficiency.

Technologies

CADEX Ceramic Bearings

Durable, ultra-hard ceramic bearings further increase hub rolling efficiency with lower rolling resistance and 1.5x smoother action than steel bearings.

CADEX Hookless Rim Technology

A broad inner rim width and durable continuous carbon fiber structure create a rounder tire shape for superior grip and handling plus added sidewall support for cornering, all without compromising on weight.

CADEX Precision Reinforced Layup

CADEX precision reinforced layup places high tensile strength carbon fiber only where needed, creating a strong, stiff structure at minimal weight.

CADEX R3-C48 Aero Hub

Precision machined 48 tooth ratchet hub with CADEX Ratchet Wave Spring offers ultra-fast engagement, reduces aerodynamic loss and virtually eliminates bearing load as ultra-smooth, low-rolling resistance CADEX ceramic bearings further reduce watt loss.

CADEX Super Aero Carbon Spokes

Ultra-lightweight high tensile-strength CADEX aero carbon spokes minimize lateral flex for more efficient acceleration and climbing and feature a purpose designed aero shape offering class-leading aerodynamic characteristics as well as superior stability in shifting winds.

Custom-Tuned DBL Technology

Dynamic Balanced Lacing technology sets spokes at a wider bracing angle and for the same tension level under pedaling force, producing a stiffer, more efficient wheel with outstanding power transfer.
