Is it possible to use Schwalbe Presta tubes on regular Brompton rims, or is the valve hole too large for the valve ring?
Yes, just use this - https://www.sjscycles.co.uk/rims-tape/mavic-rim-valve-hole-drilling-converter-insert-schraeder-to-presta/
Or use one of these stepped washers which comes with certain tubes? Pretty sure your LBS will have some if you ask nicely.
Nice one, thanks
