Bar end bolts held in by suction?

[MiniMatt]

Hi folks,

Just wanted to double check something about the bar end bolts if I may?

They're held in by nowt more than rubber suction correct? Am just putting stuff back together after the last unplanned bike/tarmac interface and as far as I can tell from disassembly of the ruined item the bar end assembly is:

Weight - rubber seal - steel sleeve - washer - rubber bung/collar - nut
(with a long bolt running through all above and the rubber seal wrapped around the steel sleeve).

Crucially, the bolt itself doesn't appear to screw into anything other than the nut, and excepting the frictional forces generated by the rubber bung and the rubber seal, nothing appears to hold the entire assembly into the handlebar?

It feels fairly solid and I doubt that it's likely to come out at high speed, but hell, if it does I'll probably wipe out in spectacular fashion so I kinda don't want to get this one wrong :D

Help, as always, gratefully appreciated in advance :D On the plus side, I have now found the ideal way to get an overly sticky-outy exhaust to kick back into line - you just need to make sure you fall to your right when crashing :D

Cheers,
M

EDIT: Oh, if it makes a difference, it's a pointy K5. In the best colour :D

Whack the fully assembled bar end in and tighten the bolt on the end, it will compress the rubber spacer and wedge it in place!

like how the screen screws work.

You know I used to consider myself fairly intelligent? Why didn't I think of that :D

It works :D That sucker ain't moving anywhere :D Well, unless I slide it down the road again...

Thanks folks :D

No probs, even I spend a bit of time scratching my head at something thats a bit obvious sometimes.
