Welcome to the sale of my Wheels Manufacturing MFG PF30-Fat-AC BB Press Fit 30 Bottom Bracket. Thie BB has not been fitted and is brand new. Comes with original packaging and spacers. I bought this in a rush thinking it would fit my bike. How wrong was I! Fits a 46mm diameter bottom bracket shell and takes a 30mm crank spindle. Grab yourself a bargain with this well engineered BB from Wheels Manufacturing. Thanks for looking
