Wheels Manufacturing valve reducers - Schrader to Presta - pair
These nifty little inserts fit in the valve hole in the rim, reducing the size from 8mm to 6mm
This allows you to run Presta (or racing type) valve inner tubes in a rim designed for a Schrader (or car type) valve
So perfect if you want to run a Presta valve inner tube such as the Schwalbe SV4 in your Brompton 16 inch rim (note the Brompton T Line and most P Line models already have a 6mm presta size valve holes)
