I got my pare cycliste bars from Blue line trailers in Boston, fitted them myself and they were quite Ok at the DREAL inspection. However, one year on I am still stuck with a box trailer I am paying insurance on but cannot use because the drawbar assembly was not accepted by the guy at Bordeaux. I thought I had a certificate of conformity, but it turns out the drawbar had not been passed and thus had no magic homologation number on it. Blue Line trailers are in process of obtaining full conformity for all their trailers, - I'm still waiting, but they say the drawbar has passed but I will have to wait until they have the whole trailer conformity before I can use the number. GRRR!! They've had several box trailers like ours registered in France with no problems in other regions. The annoying thing is that the drawbar is identical to most other large trailers I've seen both in UK and in France, we just hit the jobsworth at the DREAL in Bordeaux.. Insurance - we had to give up with Amaguiz because they wouldn't insure a large trailer. BTW we never got charged for removal of the Amaguiz antivol tracker - we do wonder whether it was ever actually fitted?
