Which of your cranks will work on my mountain bike?

ZIS Pro MTB model cranks are designed and made here at Zinn Cycles in Colorado. We put all of our crank testing and R&D into these cranks. They use a Sram GXP spindle design and Sram removable spider or direct mount chainring system and therefore will work on every different bottom bracket shell and every different chainring configuration that is available on current bicycles. You just need the right bottom bracket and chainrings and you will be all set. Below is a list of the different bottom bracket standards and a link to the appropriate bottom bracket needed to fit the ZIS Pro MTB cranks onto your bike. ZIS cranks are available in lengths from 190mm to 215mm for road and mountain bikes with single or double chainrings.

Our square taper mountain bike cranks are available in the most range of lengths and chainring bolt patterns, and they will work on any bike with a threaded BSA or Italian threaded bottom bracket. They are compatible with JIS square taper bottom brackets. Mountain Bikes need a 73x127mm JIS square taper bb.

The JK mountain bike crankswe carry use an ISIS bottom bracket, which requires a BSA threaded bb shell. JK cranks have a 64/104bcd chainring bolt pattern and can be set up with 1, 2, or 3 chainrings. We carry 160mm, 190mm, 200mm, and 210mm. Other lengths from 130mm to 220mm can be special ordered and placed with our next inventory order. JK cranks are only going to work on a bike with a standard BSA threaded bottom bracket shell. These can be used for Fat Bikes with 100mm bottom bracket shells as well.

For short mountain bike cranks, we carry the Andel Mountain Bike Cranksin 140mm and 150mm. These cranks have a standard 64/104 bcd spider, which means they can be set up with one, two, or three chainrings, depending on your drivetrain. These cranks use a Shimano Hollowtech BB system. These will work on any bike frame on the market with the appropriate bottom bracket.
