'Orion' The ultimate brake calliper! The Orion makes what was once impossible, possible. Not so long ago, no one would imagine a pair of competitive brakes could weigh less than 100 grams a pair... Unmatched mechanic values are possible due to advances in autoclave technology and the use of Aerospace grade strain-orientated pre-preg composites. All hardware is titanium, with concave surfaces, and cold rolled threads, and each calliper is individually computer tested, and documented.
