Q & A
No Hambini Bottom Bracket has ever been available with ceramic bearings. Ceramic bearings are not suitable for this application, the spindle speeds are not fast enough and the road vibration would cause them to pit the races.
Yes it will
It's a good idea, I'll have a look.
Yep, that should be within the next couple of weeks.
No It can't. you'd need a specific T45 bottom bracket. These are made to order, use the contact button if you would like one.
