It is a hybrid — a cold forged hollow aluminum arm with a \u003cstrong\u003eToray T700S carbon fiber back bone\u003c\/strong\u003e bonded to it. The aluminum handles the abuse, the threads and the crash landings. The carbon spine runs down the back of the arm and fights the flex that shows up when a rider stands and stomps. It is the first hybrid BMX crank we know of.\u003c\/p\u003e\n\u003cp\u003eThe hollow cold forged arm increases rigidity for maximum holeshot potential while staying light enough to spin fast on the track. We ran a narrow Q-factor to help that along. The hollow 30mm heat-treated 7075 aluminum spindle works with almost every BB shell type imaginable and ships with a \u003cstrong\u003eT47 sealed bearing bottom bracket included\u003c\/strong\u003e (BSA EB30 optional). Please make a note on your order is you would like to swap the BB to the EB30. \u003c\/p\u003e\n\u003cp\u003eThe removable spider accepts all 104 BCD chainrings. \u003cstrong\u003eNo chainring included.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat we changed on the new version\u003c\/h3\u003e\n\u003cp\u003eWe changed the forging tool twice during development. Anybody who has paid for a forging die knows what that costs. We did it to pull weight out of the places not carrying load and put strength back into the ones that were. The arm you bolt on is the third shape we made, not the first one that worked.\u003c\/p\u003e\n\u003cp\u003eRider input came from \u003cstrong\u003eMaris Strombergs, Kye Whyte, Oli Moran, Gaige Gomolicke and Justin Perkins\u003c\/strong\u003e.
