This is a screen shot from a Danny MacAskill video. I'm not enough of a builder of custom bikes to know what he's doing. The tool is a reamer of some type, if you watch the vid > YouTube - Danny MacAskill interview - "Way Back Home" you can see the metal chips being cut from the BB.

He is a bicycle mechanic by trade but also the world's best Trials Rider. My guess is he's modifying the BB for his riding style.
Anyone know?

Thanks Baird.
I knew about ceramic bearings but didn't know they were ever used on a bike. Learn sumpin every day. I suppose if I did riding like he does I'd have learned.
