Shortly after Interbike 2013, Wayne Moore left Ashima after quite a few years of developing lightweight brake rotors and parts. Between then and now, he’s been busy revamping the design and launching new rotors under his own company, Legion.
Two models will be offered – a one-piece and two piece. The Javelin D-Drive two piece rotors use an alloy carrier with a 420 stainless steel that are machined to nest into each other. That locksteps their rotation so the pin joining them doesn’t need to handle a load. So, he’s able to use an alloy pin rather than steel, which helps pull heat away from the rotor faster. It’s a no-rivet operation, and the pin floats freely, held in place with a star lock washer that takes about 150kg of force to pull apart.
Moore says the design is also stiffer since the pieces are tucked into each other.
