That is great advice to start off with !Unfortunately until they develop a VR bar tester it is good old trial and error... First things to try are rotate the bars slightly backwards see if that helps, then move the brake levers further up the bars as mentioned by @Guinessisgoodforyou then start looking at getting a higher rise stem and different bars.
I’ll do that
And if you’ve any pics of the type of stem and bar as fitted on a bike then I’d most appreciate it and have a clearer idea of what im looking for
