ZIS-Pro MTB cranks

ZIS Pro MTB Cranks are the ultimate in performance for big and tall mountain bikers. Available in sizes from 190mm to 210mm, they are designed and manufactured right here in Colorado out of 7075-T6 aluminum alloy for ultimate strength and stiffness. The Bottom bracket used is a SRAM GXP style and is adaptable to every major bottom bracket option on the market as of 2015, including BB30, PF30, BB86, BB386, and more. These handmade cranks are built to be used with SRAM removable spiders or direct mount chainrings, giving you the option for any chainring configuration you can think of. You can choose between a 1x, 2x, or 3x spider, or even use a direct mount chain-ring that is SRAM compatible. Spiders, DM chainrings, and bottom brackets are sold separately. Scroll to see available accessories to purchase along with your MTB cranks.

Chainrings, Bottom Bracket, and Spider sold separately. Listed price is for crank arms only with bolt kit and integrated spindle installed.

These Zinn custom cranks are designed by Lennard Zinn to be the stiffest cranks on the market. When your average customer is over 6’7″ and 250 pounds, you learn a thing or two about durability. The Zinn-tegrated cranks are the culmination of years of research and testing to find the right design for our customers. The drive side arm and spider are integrated with precisely machined contours for ultimate strength and rigidity. With the integrated spindle and external bearings, you will never again experience flex in your crank.


ZIS Mountain 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 or 73mm BB shell with English or Italian threads. If your bike has a press fit bottom bracket, we also sell bottom brackets that will allow our cranks to work on your bike. ZIS MTB cranks can be set up with every chainring configuration available. You can do 1×11, 2×11, 3×11, 1×10, 2×10, 3×10, 3×9, you name it. These cranks will also work with sram direct mount chainrings, which is the best way to do 1×11. BOOST spacing is also available, just choose a 3mm offset chainring or spider and it will work perfectly with your boosted frame. For providing clearance with short chainstay bikes or making adjustments to your chainline with 1×11 options, we offer 6mm, 3mm, and 0mm offset direct mount chainrings.
