Ok, so I got my On-One Fatty a few days ago and I plan to convert it to tubeless.
And one way to do that is to stretch a 20" BMX tube around the rim and cut it open. But I need to be able to add sealant later on as it dries out. Most BMX tubes are schraeder valves and the cores are easily removable. But all of my bikes are presta, so I'd like to stay presta if possible.
Does anyone know if there is such a thing as a 20" presta BMX tube with a removable valve core?
