Designed by Yuri Shumakov and never bettered in our opinion.
Following on from Juri Shumakov's concept designed tubes of the late 1990s, Juri set about adapting conventional Bottle Neck tubes to incorporate ridged bodies to enable a ribbed appearance to be achieved.
Again they are precision machined and incorporate a standard aft body section for locating a hook holding tube.
Each pack comes with 20 tubes
Bottle Neck Tubes have a 4mm diameter with an overall length of 13mm
