If you can deal with the unusual name; here's a chinese version: https://www.aliexpress.com/item/Top...32630895254.html?spm=a2g0s.9042311.0.0.sOOOfl I purchased one last year and have used it multiple times and it's been great, shipping took around 10 days and it mounts on the back of my R20 perfectly. I'm honestly convinced that it is just a rebranded US10 however I don't have a genuine one to compare it with. I also covered up the name with a bit of velcro.
No worries! and if you want it even cheaper you can purchase it via their mobile app for £18.37, I've just bought another one now
Yea it comes with all of the straps, if you have a look at the feedback tab you'll be able to see everyone's pictures of it.
There is a 44rewards 10% code for kriega kit. You may aswell buy new with kriega from the warranty and over inflated 2nd hand prices. Plus you are buying British (ish). Another option https://www.twistmoto.co.uk/62-soft-luggage-systems#/manufacturer-enduristan
Just took a punt on one of these. Could only find a UBB -217 but looks like you have the 215. Hoping they send me as smaller one as I have a US30 I was hoping to use it with
