Affordable "Cruzbike" Short Cranks

[ak-tux]

For those interested in affordable short cranks that are not custom made, here are some Chinese ones. Only about $45 without the chainrings.

Interestingly enough, they are branded "Cruzbike" hahaha!

Hmmm.

Other than the trademark violation, these might work very well! I sent inquiries to multiple Chinese companies about making short cranks several years ago. Maybe this is the result.

Looks like they are made by Zeroing in China and are nice-looking but poor quality. https://chinertown.com/index.php?topic=4120.0

Yikes. Having a crank bolt sheer off is bad enough, but deadly potentially on an upright where the entirety of the riders body is often bearing down on just the cranks - especially in an MTB situation.

Here in the US it would be a better bet to go with these on Amazon. Better securing method as well to avoid any shearing issues. Unfortunate name on these ones though.

Maybe something with a steel/chromoly axle is safer. These ones by Goldix are even better! They are HollowTechII compatible.

Since they are less than $50 each, one can experiment and test them.

Here is one more variation:

For those interested in these short cranks and need an affordable spider based power meter to match, they can combine these with something like these 3bolt Xcadey ones:

All in all, they can make for a good budget option: https://www.aliexpress.com/item/4000126830286.html

The Goldix with a chromoly axle? Great!
