The Good: 22mm spindle and solid aluminium is the way to go! Much better than the Primo power bites or hollow bites with the 16 spline spindle. Super cheap compared to chromoly cranks.
The Bad: People sometimes have problems getting pedals stuck, Shadow tells you to grease the pedals bosses. Doing so doesn't cease the pedals.
There are no better cranks and if you're on a budget, they're even better!
