BB shell threads worn
I recently got an alloy frame and as part of my frame prep chased the threads in the bottom bracket, fitted a shimano bb to the specified torques. ( Think it was 40 nm on Drive side and 15Nm on non drive.) After a few moderate rides with some steep uphills I felt some play in the bottom bracket. The cartridge had worked its way loose and when I striped and inspected the bike the threads in the BB shell were worn down. The BB cartridge threads were fine. Does anyone have any idea if I can save this frame?
