"Draught" Beer Cap Bar End Plugs - By Mucky Nutz

Such a great product it almost needs no description, the picture says it all. But anyway...

These use an elastomer expander to grip inside the handlebars. The advantages being: -

* They will not come out by hand, tree or rock.
* They fit all handlebars with an inner diameter of 17mm upwards


Stick these 'draught' plugs into your handlebars. Tighten them up! Now drink! Have a beer! Then have another! Recycle the bottles! Then stick the tops on the Bar Tabs!! Jobs a good'un!
When too many trees have jumped out in front of you and scratched the tops to death simply change them for another pair.
For all those sceptics out there, the Bar Tab is wider than the bottle top (30mm) so simply apply a bit of common sense when fitting them and you won't shred your hands!
These use a black nylon end cap (to fit your bottle tops on), an elastomer expander, and stainless fasteners.
