Short vs. Long MTB Cranks | Physical Therapist Perspective

Considering short MTB cranks? Watch this first. Here's a non-sponsored take on mountain bike crank length. I've spent a considerable time on 170, 165, 160, and 155mm cranks, and I'm nice and opinionated on where I think the industry should be heading with MTB crank length.

I'm well aware that the only brand shown here are 5Dev cranks, but again this is not a sponsored video. I just like their cranks personally, and we do sell them out of our shop. The options are quite limited at the moment for cranks below 165mm, and 5Dev make a solid option. One thing I really like is the removable spindle on their cranks. This is handy if you have 2 bikes with multiple hub widths (i.e. regular Boost 148 spacing MTB and a fat bike with 197mm spacing, they offer different spindles so you can just have one set of high-end cranks for both bikes.
