The Good: These cranks are light, strong, and can take any abuse you throw at them. I have had these cranks for a year now I haven't run Into and problems. The metal backplate on the crank arms look good and add a lot of strength to the cranks. They have a beefy 22mm spinal with hollow bolts.
The Bad: The paint rubs of the arms easily if you ride a lot. I would suggest getting mid top shoes because these cranks hurt your ankles.
Spline drive is only compatible on one side.
