Is anyone familiar with Mannesmann steel tubing? I was looking at the current Viper frame (comparing it to circa 2000 one I own) on the Basso website and noticed the specs list "Mannesmann tripple butted steel custom shaped tubes". I seem to recall this brand of tubing being used many years ago but didn't think they still were in the bike tubing business. Anyone here know the story on this stuff? Maybe they have a bunch of NOS tubing at Basso?
My Viper doesn't have a tubing sticker (except for the one that says "Basso tube concept") but is supposed to be OS Deda Zero.
