Useful thread, couple of updates for anyone looking to do any of the above.
The rise won't 'properly take a 203 rear disc, with the correct spacer the pad still sits away from.the discs by probably 4mm. Orbea actually state that you can't put a 200 on the back.
To remove the chainring on the ep8 rs (maybe the 2023 model only) you need a lock ring tool for a 42mm ring not the park tool one stated above. That is too big and won't work. Shame as I bought the parktool and 203 disc/spacer for the rear and neither work . Still super useful article. I am putting a 203 just on the front now and seeking a 42mm BB tool.
