After six months here is my review of the 155mm Canfield cranks and my review of an Absolute Black oval chainring

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 researched 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).

Here is my first blog article on the subject:

This study showed 145mm cranks produce the most power: https://pubmed.ncbi.nlm.nih.gov/11417...
This study found a very small difference between 120mm and 220mm cranks:
