CTg BRAKING SYSTEM
CTg Carbon Clincher Braking System: The Confidence to Perform
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 tires. 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.
The team at the RCS has been designing, testing and riding carbon clinchers longer than any other brand. Since developing the first carbon clincher wheel more than 10 years ago, the RCS has continued to lead the industry in performance and safety. Reynolds’ unparalleled experi-ence, engineering skill and uncompromising standards result in wheels that give riders the confidence to perform at their best.
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.
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.*
The Benefits of CTg
Cooler rim temperatures giving riders enhanced braking performance, better brake modulation and improved rim durability in every braking situation.
Paul Lew, Director of the Reynolds Composite Studio, invented the first commercially available carbon clincher wheel. In the 10 years since, Reynolds has accumulated more test data and has developed more applied technology than any other bicycle wheel manufacturer. The CTg system was developed by Reynolds to harness the very best new materials and improve product performance.
The engineers of the Reynolds Composite Studio, including Lew, are cyclists themselves. They take carbon clincher reliability and safety personally – especially in the important area of braking-induced heat build-up.
The Reynolds Composite Studio features a modern product-testing lab with the latest fixtures and instruments that measure aerodynamics, fatigue, temperature, and heat dissipation. Reynolds Cycling has built up industry-leading safety standards with its testing protocols.
In this test, conducted on August 15, 2012 at the Reynolds Composite Studio in Sandy, Utah with a Fluke Ti32 Thermal Imager, thermal imaging clearly demonstrates that CTg Brake Tracks and Cryo-Blue Pads work effectively together to produce dramatically cooler braking temperatures.
