Kettle Cycles fantastic new rotor

Barely heavy enough to register on the scales, Kettle’s flagship rotor weighs just 40g

A bicycle rotor that is light weight, wear resistant and has superior heat management. Sound good?

What is SiCCC?
SiCCC, is a Silicon Carbide, Ceramic, and Carbon fiber braking material developed specifically for cycling. Our goal from the start was to create a more reliable, better wearing, lighter weight brake rotor. Silicon Carbide for friction, Ceramic for heat, and Carbon fiber for strength.

The SiCCC disc rotor braking surface provides a level of power and progressive feel that equals or surpasses the best conventional rotors. The progressive power is excellent; not much lever effort is required, and the response is quick but not over-the-bar grabby by any means.

The SiCCC disc rotor braking surface is a non-metallic composite and it is thermally inert, meaning it doesn’t expand and contract as all metal rotors do. There is no heat-induced stress distortion on the disc.

The rotors - dubbed SiCCC after their manufacturing components (Silicone-Carbide Ceramic-Carbon) - are distantly related to the sort of carbon fibre used in high end frames. Instead of using an epoxy plastic to keep the carbon fibres together though, a silicone carbide binder is used that is much more heat resistant, and has the friction properties necessary for brakes. The technology used in the SiCCC rotors has been around for a few decades in space shuttles, formula one, and even features in a few exotic production cars. But until now, no serious attempt has been made to implement the composite into bike discs. Kettle says that the rotors are equally responsive in wet and dry weather, and won’t need to heat up to be effective – a problem that plagues the same technology in car racing applications. Despite seeming more fragile than metal rotors, Kettle says that the longevity of the SiCCC rotors has far exceeded expectations. The rotors are rumoured to wear at a much slower rate than their metallic counterparts, and are thermally inert, meaning they won’t expand and contract. Kettle expects to deliver two different options. The SFL (or Super Feather-Light rotor) is their flagship, single piece unit and is made entirely from the carbon ceramic material, weighing just 40g for a 140mm rotor. A two-piece riveted disc, with a conventional carbon-fibre spider is also planned. While slightly heavier, the two-piece rotor will cut cost by reducing the amount of carbon-ceramic material used.
