While making brake rotors from aluminum would seem to be an easy task, it’s far from simple. He says he spent about four years working on materials and designs before introducing Scrub rotors last year. LaCasce recognized that steel brake rotors are among the heaviest single parts remaining on a mountain bike and had great potential to be made lighter. “That’s what pushed us if you look at bikes now, there are not many places left where you can make big improvements,” LaCasce said. “I was always tinkering and throwing ideas around,” LaCasce said.Īfter completing his degree, he decided to have a go at the cycling market with a product that few have attempted. LaCasce is an engineer by education and has been an avid cyclist for the last 15 years. In business for just more than a year, Scrub Components is based in Park City, Utah and is operated by Chris LaCasce. We spent more than 100 miles on a pair of Scrub rotors to find out. That’s fully a third of a pound.īut does that kind of weight savings come at a cost? Financially, yes: A single 160mm Scrub rotor will lighten your wallet by $145. A comparable stainless steel rotor weighed 135 grams, meaning that by swapping rotors alone, you could shed around 150 grams from your bike in one fell swoop. Fully half the weight of a traditional 6-bolt stainless steel rotor, a 160mm Scrub rotor weighs less than 60 grams (56 grams claimed, our test rotors each weighed 58gm). Most components seem to have reached their limit in the three-way, strength-versus-stiffness-versus-weight tug-of-war.Ĭhris LaCasce and Scrub Components want to change that, with Scrub aluminum brake rotors. If you are a weight weenie (and there’s nothing to be ashamed of if you are), finding new ways to save weight on your mountain bike is getting harder and harder. Shiny and new, Scrub rotors have a machined brake surface for smooth performance.
