ITA Italian Thread Bottom Brackets

ITA (Italian thread) bottom brackets fit 70 mm threaded shells with 36 x 24 TPI threads, right-hand on both sides. You will find ITA on many Pinarello and older Colnago, Bianchi and Wilier frames.

Pick the version that matches your crank spindle: 24 mm for Shimano Hollowtech II, SRAM DUB, or 30 mm. Ceramic options reduce friction; steel options are the durable, budget-friendly choice.
