Had a fright this afternoon when trying to remove the bottom bracket from wife's Litespeed frame. I spent close on half of an hour trying, and even wrecking the BB cups machined teeth. Finally got it off after much panicking. It looks as though the BB's alloy thread had galled to the titanium BB shell judging by the residual white powder left.
The bike has been ridden year round but with a change of components for the winter months – my old 9spd Veloce group set and wheels used for winter riding – plus use of Crud catcher mud guards.
I only installed the centaur BB last Summer using a light coating of Superlube grease (and to correct torque). From now on will be using Copper Slip Ti prep paste regardless of riding conditions.
Just thought would make others aware that it can and does happen.
If the worse had of happened and BB could not have been removed are there any frame builders in this country that could actually work with titanium? There are none that I know of
