Details just in from 24pouces, sounds a great event.
I organize in France the "mtb retrobike meeting" in the beginning of July. (it's the second time)
This year, 4 members of retrobike are interested for coming : Trip from Spain, Oneshnark from Germany, and the OWMTBC team, Mr Kawa and Ned.
If you want to come, you're welcome and invited. It's a preparation too for a big meeting in France in 2012 (The 25th birthday of the first international mtb race in Europe. It was in french Alps…)
