After over a year of being out of production, the little SX cranks have found a new home with Speedline Parts. These are the same SX mini cranks that you have loved over the years, CNC Machined 7075 T-6 Billet Aluminum Arms, with a replaceable spider that allows you to run either a 5 Bolt Spider, a Solid Chainring, or the new 4 Bolt 104 Pattern Spider for an even lighter set up than the original ( Only 350 grams for the 2 arms, and 4 bolt spider in the 145mm length ). Currently the Speedline SX Mini Cranks are available in Black only in
sizes from 135-170mm in 5mm increments. Pick up a set at your favorite BMX dealer today. And the great part is that these California CNC Machined Cranks are only a $150.00 MSRP and work with your existing square Taper BB set. And while you are there check out the full line of Speedline Parts for your bike. From Carbon Fiber headset spacers, to Hollow Pin Chains and everything in between.
