2x Schrader Drilled Rim - Presta Valve Converter Adapter Reducer Grommet Stem Saver

 

Do you want to use Presta Valve tubes but your wheel rims are drilled for Schrader Valves?

Then these converters will reduce the hole size so you can.

Made from a hardwearing resin, they just push in and hold firmly in the hole.

• Pack of 2

Please note!

There are a very small number of tube's on the market like Tubolito and others brands with plastic sleeves on the valves.
These specialised tube valves will not fit these adapters as their valves are non standard and much wider than the standard Presta Valve specification
In these circumstances customers have reamed the adapters using a drill bit but its not something we have tried or would recommend.
