### ⭐ Wrong size shown?
*by S***B on August 1, 2025*

I confirmed my bike’s dimensions for the rear axle (3/8” x 26tpi) matched this product description. But they don’t fit right. I couldn’t get them all the way on and now they’re stuck in place! Trying to loosen them with wd40 but still not working :(
