These are then finished with anodised aero grade aluminium end caps in a multitude of colours.
Carbon bobbins can be purchased with isotopes pre fitted (12.0mm x 3.0mm) 
or alternatively fitted with a slot so an isotope can be fitted at a later date.
 
The kits comprise of stainless steel ball clip, 6 inch black chain and hockey stick along with alignment o rings.
