My RTS needs a new clamp and the seat post appears to be 26.8. The exterior diameter of the seat tube has some fractional ovalisation and varies from 28.5 to 28.8. Does anyone know what clamp I should be looking for ? Was it something standard ? I only want a plain black allen bolt one to go on there so it doesn't need to be fancy.
