The aerodynamic benefits of DET™ require fewer watts to go faster and inspire confidence in technical criterium courses, winding roads and descents that dreams are made of.

Dispersive Effect Termination
Dispersive Effect Termination (DET™) is a revolutionary rim shape designed by
Reynolds Cycling, and applied to its new line of wheels, the AERO. DET™ smoothes turbulent, excited, energized airflow and re-attaches it to the aerodynamic surface, effectively reducing aerodynamic drag. It also challenges the popular perception that turbulence in the boundary layer of a bicycle rim is beneficial. Instead, the unique “V”-shaped rim is designed to minimize airflow turbulence. Rims featuring DET™, at 26.2mm, are wider than competitor rims. This width rim removes the “balloon effect” caused by wide tyres on narrow rims, gracing the cyclist with better cornering, decreased rolling resistance, and a more comfortable ride. The 26.2mm rim width fits all UCI approved road and all triathlon 2011, 2012 and 2013 frames.

CTg Carbon Clincher Braking System
CTg is an innovative braking solution developed by the engineers of the Reynolds Composite Studio (RCS) to give riders utmost braking confidence in their wheels. The carbon fiber clincher may very well be the perfect wheel: it’s fast, light, and strong, with the added benefit of convenient-to-change tyres. Yet there is a challenge in creating a carbon clincher that stands up to rough roads, stresses imparted by the rider, and heat build-up during extended braking. Designed as a fully integrated system, CTg (Cryogenic Glass Transition), is Reynolds’ patented carbon fiber rim-and-brake pad pairing that allows Reynolds wheels to run up to 53% cooler than standard (non CTg) rim-and-pad combinations. CTg ensures smooth, predictable braking performance, enhanced safety, and industry-leading dependability.

The CTg brake track unlike other brands that order off-the-shelf, Reynolds formulates its own proprietary carbon fiber laminates and specifies only the highest grades of resin systems for its rims. With this arsenal of differing carbon fiber lay-ups and high-performance resins, Reynolds engineers arrange laminates in optimized layers to create the CTg brake track. These layers extend into the rim, effectively creating a heat sink. Heat dissipates away from the surface, to be cooled by the passing air.

To Reynolds engineers, it was logical to develop brake pads in conjunction with their rims due to the critical role that both play in braking performance. Made of proprietary polymer compounds, Reynolds’ Cryo-Blue pads are designed to work specifically with the CTg brake track. Together, the combination of brake track and pads reduces rim temperatures by up to 220° F versus other manufacturers’ carbon-specific pads.
