There’s some terrific riding in the Chamonix valley! I went over on a group holiday with a company called Rough Tracks, which was then based in Calne, Wilts, where the print company I worked for was based, so we did all their print. One of their brochures had me in a couple of the photos from a previous trip out to the Parc du Volcans. Wonderful weather and stunning scenery. IIRC, I was riding a Cannondale Beast Of The East with a pair of the original Marzocci Bombers, the 100mm ones with orange sliders and disc mounts on both forks.
Would have been mid-90’s ish or so.
