I have a used bicycle inner tube that needs a new home. The size is 650 -18/23C, the ETRTO diameter is 584/590mm. This smaller than the more common 700C tyre. It is also not compatible with 26” mountain bike tyres. In great condition and has not suffered any punctures.
To be collected from Ruddington.
