Review on 🏞️ All Mountain Style Crank Defenders – Enhance Protection and Style for Your Cranks by Will Bremer

After hearing from the manufacturer that the product would fit my Dura Ace 9000 crankset, I ordered it. After warming up, the boots can be easily slipped onto the cranks and the holes in the pedal axle connected. In this issue I noticed that the boots sit a little wider on the inside of the arm, so in the lowest 3 gears the boot touches the chain 2 times per pedal stroke. Of course, this isn't an issue with the 1x drivetrain or non-drive side, but you get friction with tighter road/CX/gravel settings. I shaved the inside of the boot to the point where I could see the crank before getting the clearance it needed, but it still seems pretty well protected so I'm fine.
