On-One Inbred 29" winter ssmtb I won't use

Honestly, no idea, probbaly a tester question.

Plastic can be pretty strong if used in the right context. Those look pretty burly, and the most you can put on a Blackburn any-cage thing is 4kg. Let’s be honest though, who’s putting that much on them? Most people are using them for sleeping pads and sleeping bags etc. most of which are probbaly well under a kilo.
