The above mentioned "Potato chipper" is only sold by M-Tec in Germany, but they deliver all over Europe. Ordered it yesterday by fax, got an e-mail today it was posted!
The perspex headlight protector is a Touratech article.
The standard adventure headlight protector has two clear disadvantages; I know off several ppl who lost it while riding,
because it's not bolted on! The second disadv is even bigger
potato-slices..
About the small stones coming through the wire; I had a similar
construction on the H&B crashbars, and in several years off use,
no stones came through, no "loose chippings" in Ireland, and no
Spanish, Icelandic or Norwegian gravel...
