I need to buy 100% carbon fibre tubes 26mm inner diam x 31mm outer diam x 110 cm long to built custom made spearguns . 

Which is the strongest manufacture procedure  regarding stiffness between Pultrusion and Roll Wrapping please ?

Thanks and best regards

The rods are only pultruded.  If you are looking for tube, roll wrapped is the better all round choice as it has better hoop strength.  I would still be concerned for failures as composite splinters into pieces.  You may need to ensure your designs have a large safety factor in them to ensure that does not happen.
