Removing Vintage Bianchi Fixed Cup
Ok my problem is I need to remove the fixed cup so I can remove the chain guard bracket. The problem is that the lip of the bracket prevents using a standard BB tool. Is there a special tool for this? Also is this a lefty loosy/righty tighty or reverse thread on the drive side? I spent about an hour at my local LBS and tried every tool he had with no success. Any help is much appreciated. V/r Shawn

DIY tool ..
Bianchi USA, has long ,several decades, used Asian OEM Factories, Got the Left one out ? what is it ? British thread,* I expect, then the fixed cup is Left hand threaded..
*1.370 x 24 tpi _ Italian thread is bigger ; at 36mm [metric equivalent of 1.37" is 34.8mm ]
Only Italian Bianchi would be importing (a very few) race bike frames.. So no chainguard..
