We make this cage in plastic also but the carbon one is the way to go. @Timarchylime I might have one of these in the correct side for your st cage if you’re interested. I can not guarantee when it arrives though (as my secret santee can confirm).
The bars swing to just perfectly hit the TT on the end. And the endcap is hard plastic at the moment. I’m hoping all of this will change when I get it set up better.
Got some 50mm tires and a surly 8 pack rack on order.
