legion-javelin-D-Drive-two-piece-brake-rotor01

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.

Dovetailing the parts together means the rivet doesn’t need to use as much force to keep them connected, allowing for a true floating design. Moore says that means less distortion, so the rotor is more true.

The Discus one piece rotor squares up the aesthetic of Ashima’s Ai2 rotors to eliminate any pulsing. He also switched from using 410 to 420 stainless steel, making it harder and stronger. The dual leg design means it should be stiffer, too.

His new brake and shift cable housing is 40% lighter than standard thanks to swapping out most of the steel cables for aluminum. Five are steel (darker ones) to keep it strong enough under compression, and 12 are alloy to save weight. The brake housing gets the Kevlar wrap shown here to ensure firm braking.

thank god someone answered my prayers and is making lighter cable housing

how exactly is the kevlar making braking more firm?

He left Ashima and started a company named Amisha? That’s either bold or cocky. My guess is cocky. Nice looking rotors though.

@radeus, The article may have been edited since you read it, as I know the timeframe for these interbike posts is fast and furious, but the company name seems to be Legion, not Amisha…which would be a pretty bold move!

Wayne has come up with some pretty creative designs in the past, although the actual performance advantage of some of them seemed questionable. I think I saw some test data from his co. at one point on heat dissipation of his alu/steel sandwich rotors that were kind of a different take on the Shimano Ice Tech design. I would love it if he would publish some more test data on these things, including just how resistant to compression is that cable housing compared to some benchmarks.

I wish more bike/components companies would adopt Apple’s strategy of not showing a product until it’s ready. As it stands, Interbike is more like the CES show, in which vaporware reigns supreme.

If I need a part now, and read about a potential solution offered at Interbike, only to read, “Bob Widgets hopes to have the part ready for sale by November 2023,” then my (deleted), I buy another part, and Bob dies a slow death.

Its definitely Amisha Ltd.

Go to the website for Legion at the bottom of the article… the title of the home page is Amisha ltd., and it has Amisha ltd at the bottom next to the contact info too.
