I posted on here before asking if anyone had experience with using a front rack. The lightest and best value option I could find was this titanium one from overseas.

And then I bought the 25in Voile rack strap – https://www.sjscycles.co.uk/luggageluggage-hooks-fittings/voile-rack-strap-orange-black-25-inch/
Voila. The perfect solution. Gets my pack off my back which is more comfortable and far less sweaty. Costs less than a Brompton bag. And supremely versatile going forward with different carrying requirements in the future.
