I have some lights and a cycle computer that attach using some sort of rubber or silicone bands (or O rings - don't know what they are called). I need some replacements, but I don't know what they are called!
Best I can find on (say) Amazon are O rings that look the same but seem to be only for plumbing - not long term daily use on a bicycle.
I need various sizes as I want to move stuff between bikes - which have differing tube/handle bar diameters.
The technically right name - or a recommended supplier - would be most welcome!
