Review on Grin Technologies Universal REAR Ebike Torque Arm: Robust 1/4 inch Stainless Steel to Safeguard Ebikes from Axle Spinout by Matt Woodward

I was skeptical about buying this product because there are much cheaper alternatives, but when I received the package I knew I made the right choice! It's not a thin piece of aluminum, no - it's cold, hard steel. Installation was a little tricky for me because I already had a rear rack installed which saved me space, but I figured it out eventually. This is a one-time investment that you will not regret!
