ZIS-3 integrated spindle road bike cranks

The ZIS-3 cranks are the culmination of years of testing different materials, finishes, and designs. The ZIS-3 has surpassed any other crank on the market, including our own ZIS-2, in durability, stiffness, and fatigue life. The ZIS-3 cranks are made out of a 2024 aluminum alloy that provides the most strength and durability available. Our previous model, the ZIS-2, surpassed the EN standards for durability by more than 4x. The ZIS-3 has beaten the record once again with unlimited revolutions in the testing facility, making it one of the most durable cranks on the market. Tall riders using long cranks can apply an enormous amount of stress to a crank, particularly when using extra-long pedal spindles that professional bike fitters recommend for many big riders. The ZIS-3 cranks are designed to not only withstand that but also to harness that power you apply to the pedals and send you to the front of the pack. Aesthetics are also greatly improved on the ZIS-3 cranks due to our shot peened, polished, and bright-dip anodized finish. ZIS-3 cranks are the most high performance bicycle crankset for the big and tall rider available. Our integrated spindle custom road bike cranks use the same 24/22mm stepped spindle and external bottom bracket as SRAM and Truvativ cranks, which provides excellent performance and easy service. As well as ease of finding replacement parts. We have a variety of bottom brackets that will improve your performance and also make your Zinn cranks compatible with virtually any bike in the world. See below for bottom bracket compatibility information. All ZIS (Zinn Integrated Spindle) crankarms are 100% handmade in the USA with American materials. We use the best 2024 aluminum alloy for ultimate fatigue life. The CNC-machined and bright black anodized surface finish is unique and beautiful and shows the high quality craftsmanship that is put into every single crankset. Currently available with 110mm BCD (Bolt Circle Diameter) compact-double spider arms. Chainring options for a 110bcd crank are 34/50, 36/52, or 38/52. Order now!

ZIS road bike cranks are compatible with a number of different drivetrain options. The cranks use a SRAM GXP external bearing bottom bracket and can mount to any bike with a standard 68mm BB shell with English or Italian threads. The five-arm spider has either a 130mm Bolt Circle Diameter (BCD) or a 110mm BCD pattern for chainring compatibility. Zinn cranks are not compatible with Campagnolo chainrings, but they fit any standard 130mm BCD or 110mm BCD chainring. If your bike has BB30 or some other type of unthreaded bottom bracket, chances are that there is a bottom bracket that will make our cranks work on your bike. Click here to view all available bottom brackets and adaptors. ZIS road cranks can be set up with 2×10, 2×11, 1×11, or 2×9 chainrings. SRAM or FSA chainrings work best. Zinntegrated Road cranks work with singlespeed, belt drive, and internally geared hub systems.
