What would be the lightest BB set up for a carbon air 9.
I currently have a RaceFace Turbine SL 2X10 crank with a 24mm spindle
Wheel manufacturing makes Delrin inserts
Niner makes Different cya inserts
Raceface makes different bb
What combo would be the lightest?

Any thoughts ?

Not sure if it exists but a "press in adapter" that holds the bearings would be the lightest. The stock setup is a press in for the frame that has threading, then your BB threads into that. But if they were one unit then it could be lighter.

Niner has a press in threading for BSA or BB30. You probably have the BSA. So changing the insert for a BB30 is just going to make things more expensive.

I'd say get a lighter BSA BB that has ceramics in it. That could drop weight but its not going to do much.
