This review is two years in the making…
I’m always curious about the many standards in the bike industry and how slow the industry is to change. I wrote articles about wide bars, short stems, slacker head angles, wider tires, and longer frames years and even decades before the big bike manufacturers all made these changes to their bikes.
Crank length is another one of those tradition-based industry standards with no science to back up the standards. I have reached what little actual crank length science is out there and spent the last six months riding little, tiny 155mm cranks (despite my 35.5-inch inseam).
After six months here is my review of the 155mm Canfield cranks and my review of an Absolute Black oval chainring:
Please share this article with anyone you think may benefit and feel free to call or e-mail with any questions.

Steve from hardtail party did a good video using all the crank lengths from Canfield, it’s worth a watch. https://youtu.be/h7sKhKi9Bcc
I went to 170’s with my 38″ inseam with no issues, I’ll have to try some shorter ones after watching your video.
If you think about, when you shorten your cranks you’re basically going to a steeper seat tube angle as well, at least as far as putting more power to the tires. At 3 and 9 where you power is strongest and you go from a 175 to a 155 you’re basically adding 2 degrees to the seat tube angle (from what I’ve read as a general rule, seems about right).
