612 Track Cranks
I've been riding the sample 612 Track Cranks since early September, and I am happy to report that they've held up great and are the best cranks for freestyle that I have ever ridden.
They are stiff and burly and have survived all the punishment I have been able to dish out. I have also become a big fan of the large square side sections which are great platforms for any kind of trackstand trick where you need to balance on part of the crank arm. As you can see from the photos of my abused Brooklyn, they have also withstood the salt and nastiness of the Minnesota winter with grace and charm.
I feel like we've made the right choice for our first crank offering with these; they are stiff, durable, and fairly inexpensive at $124 MSRP. This forging is available in a multitude of configurations from the manufacturer (which is why you may see variants on the market from other brands) and we have chosen what we believe are the strongest and smartest of the available options to carry the All-City name.
First and most importantly, the 612 Track Crank is cold rather than melt forged. Cold forging allows a better grain structure in the alloy, which in turn yields a stronger and more durable part. The cold forging process also provides a harder finish, making it less prone to scrapes and scratches. Secondly we have chosen a classic finish and shape for our chainrings (ships with a 46t ring), rather than the blocky "chainweel" style you often see on track rings today. These features add a bit to the price, but in the end we feel lthat it's well worth the extra price for a stronger crank, that looks great, and will continue to do so for a longer period of time. If you need a stiff and strong, 144 BCD track crank, give the 612 a shot. The first shipment is due sometime in late January.
