That’s the "Assiolo": my first MTB singlespeed. My goal was to build a reliable and "as simple as possible" off-road bicycle. So I started from a "vintage" Tommasini bike, repainted by myself and renamed “Assiolo” (a local owl). As well as renaming the bike, I assembled it mainly using components from my gar(b)age.

Technical specs. Frame: Tommasini Sincro Pro, TIG-welded Columbus Off Road Nivacrom tubeset Fork: Fimoco E129 (with reduced travel to minimum, around 10mm?) Wheels: rims Mavic 139, front hub Fimoco DH, Rear hub Xtr, tyres Ritchey Speedmax 1.9 Stem: Specialized Ti. Handlebar: Azonic Double Wall Seatpost: unknown but nice; Flite Saddle Brakes Avid, rear brake arch Fimoco AL6061 Crank Ritchey, chainrings 36 x 20 (no chain tensioner)

Just two words about Fimoco: it was an expired factory near Grosseto which realizes in the '90s mainly XC and DH forks, and secondarily DH hubs, cranks, brake arches, which were made using CNC technology. They were small pieces of art in a MTB golden era ('90s).
