Space-Grade Cranks Are Out Of This World

5DEV Road and Gravel Cranks are engineered for the long haul, pushing your road or gravel drivetrain with power and precision.

These cranks bring the 5DEV custom, industrial MTB style and performance to your drop bar or hybrid ride. They're a bit lighter than their MTB counterparts with longer arms more conducive to slower, smoother cadences. These cranks, like all 5DEV products, are made by hand with aerospace grade materials in San Diego California.

These are offered with the standard road BB width of 68mm as well as the 73mm MTB width. Choose from 170 or 172.5mm crank arms.
