I have recently purchased a Fifteen G crankset to install on an new Ibis Tranny frame. When I try and install the BB adapters (by hand) they are only threading a few turns and then stopping
- Neither drive side nor non-drive side will install.
- Threads have been properly greased.
- I have an old Shimano BB which installs with no issues.
This is a brand new frame and although the BB shell has not been 'chased', the easy installation of the Shimano BB would seem to indicate that it is not necessary.
Could you please advise where my problem might lie
