Works with Wheels Mfg BB86/92 bottom bkt

I've put it through the wringer
True to size

This socket is well made. It DOES work with the Wheels Mfg BB86 / 92 bottom bracket, backcountry p/n WHL000Q.


Will this work with a BB with 48.5mm OD? Need to know if this works with your Item WHL000Q, Wheels Mfg BB.


Is the BSA30 a 12 or 16 notch socket?

Hey Derek, there is a 16 notch version of this bottom bracket socket and also a BSA30 version that works with a threaded BB30. Hope that helps! Feel free to email me with anymore questions at mbova@backcountry.com.
