Any one any experience with Advpro. Have a set of Moskomoto back country soft panniers. These plates look to be the answer to not fitting an additional fram to the GSA. Looks like most of the alternative option to oem panniers all sourcing from Europe.
When I contacted them they wouldn’t ship panniers or top boxes to the UK as it was too much hassle and paperwork for them. They would only ship small accessories etc.
