Italian thread BBs are a specific find for a specific frame \u2014 if you&#8217;re running a Pinarello, Bianchi, Colnago, De Rosa, or other Italian-thread frame with a Hollowtech II crankset, this is exactly what you need and they don&#8217;t come up often in this condition.<\/p>\n<p><strong>Workshop Wisdom<\/strong> \u2014 Italian thread is 36x24mm and both cups are right-hand thread \u2014 no reverse threading to fight with unlike English\/BSA. Clean the shell threads thoroughly before installation, apply a thin film of grease to cup threads, and torque to 35\u201350Nm. A properly installed Italian BB should never creak.<\/p>\n<p><strong>Guarantee<\/strong> \u2014 You put in the miles, we put in the work. 30-day guarantee on fit, function, and condition. \u2013 Paul<\/p>\n<p><strong>Keywords<\/strong> \u2014 Shimano BB-7900, Dura-Ace bottom bracket, Hollowtech II, Italian thread, 36&#215;24 ITA, 68mm shell, SM-BB7900, road bottom bracket, Pinarello BB, Bianchi BB, Colnago BB, De Rosa BB, Italian frame bottom bracket<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Will this work?
