Hello,

I got a Cipollini frameset from a friend and tried to build it up. The bottom bracket type is BB386Evo. It came with two plastic cups to reduce 46mm shell (386Evo) to 41mm diameter (BB86/92), so that Shimano SM-BB92-41B bottom bracket can be installed for Shimano crankset.

The plastic cups were cracked when my friend tried to removed crankset. Thus, I need to find replacements, however, the cups don't have any brand/model info. I tried to google but nothing came up. Searches only showed adapters to support different crank types, but nothing for different bottom brackets.

Please, let me know where I can find such reducers/adapters. Thanks in advance for your helps.
