Somehow I've managed to loose the bolt from one of mine.

If anyone finds it please shout up.

Alternatively if you know what it is please tell.

Thanks.

I will when i get home and i can get a replacement for pence +postage

My mistake I have bar end ones so the GP2- though they all had bar ends,

However this wesite says M5x15: for GP1,

I suspect it will be 10-20 p for one from the local nut specialist - which i can get if you dont have one near by and post at cost .

Cheers for the info.

I'll be able to sort.
