I had a Lapierre X-lite 400 FDJ. Bought it purely for the design and color scheme. It developed a crack on the inside of a chainstay after a year. Since it was secondhand, I did not attempt to warranty it. I'll send it over to Calfee for repair on a whim one day.
Oh as for the frame itself... The one standout was the very nicely tapered, oversized headtube with a beefy tapered fork. The one quirk with this race-oriented frame was that it had a comparatively tall headtube. I would love to rebuild this one day.
