We offer pre-cut threaded rods which are ready to pound into the frame or sub-frame of your bike to stiffen the rear when using our subcage products.
We have found these to be the most effective and relatively cheap way to stiffen the frame...

Z125 subcage and frame stiffeners
They worked great and their online video is super easy to follow along with. I ordered the raw version of the subcage and it shipped and arrived super fast. The subcage is very secure and tight. Doesn’t wiggle or wobble at all when standing on them.
I will say when installing the frame stiffeners to get a metal brush with a long handle and run it in and out of the frame slots as I did not do this on the first one I installed I just cleaned the very edge of the inside. It took about 30 minutes of beating on it to get it all the way in. The second one I installed I used a metal brush to clean the inside with and it went in really easy.
I 10/10 recommend this setup with the stiffeners to protect your frame.
