Collection: carbon fiber tube 31-40mm

Carbon fiber tubes between 31mm and 40mm outside diameter, for structures that carry real load — large multirotor booms, robot arms, and frames where a thin wall would flex too much.

Each listing shows the bores available. At these sizes the practical question is usually how much wall you can afford in weight terms, and that is set by the bore you pick.

500mm and 1000mm lengths as standard.
