Swiss Stop Catalyst Disc Rotor
SwissStop Catalyst disc rotors deliver consistent brake torque over long durations where others experience gradual decline and brake fade. Due to extremely efficient thermal management, Catalyst provides notably shorter stopping distances with very low wear rates under hard braking, exceeding the current industry leaders.
 
Features
  • Optimum heat dissipation for maximum braking endurance and shortest stopping distances 
  • Reliable performance from cyclocross to downhill
  • High durability, even in he toughest conditions
  • Lightweight 7075-T6 aluminium spider
  • Highly efficient SUS410 stainless steel brake track
  • 6 bolt fitment
  • 110-198g
I run these rotors with Campagnolo Potenza hydraulic calipers and levers using Campy pads (manufactured by Magura). I also use them with Campy Chorus EPS levers and mechanical TRP Spyre calipers. I mention this because I think rotors can only be rated within a system. This is the best rotor I have ever used when considered within these two systems. I think they would work equally as well in other systems. Braking for my 160lb body seems unlimited with 160mm front and 140mm rear. I like to brake late and these rotors inspire confidence on road and in cyclocross. Swiss Stop claims a lot of research went into these. It is a company focused on braking and I have always trusted their products for this reason. These rotors do not disappoint. Wear indicator, rounded edges and cross hatched surface, things that indicate attention to detail. I've used Shimano, SRAM, TRP, Avid, Ashima and other rotors, looking for the trade off between rotor weight and performance. For my setups, these are the absolute best rotors I have used both in terms of overall stopping performance, initial bite and cooling. They are not cheap, but they are worth the premium over other rotors.
Fitted yesterday and stop like a dream
Easy to fit and do the job. Seem to be working well.
Expensive discs but amazing stopping power. Significantly better at braking than the stock ultegra discs that came with my bikes ultegra hydraulic brakes. If keen braking is a priority, then these are well worth the investment.
