FYI: This is the model SOMA/Merry Sales recommends for threading switches. They sell Italian, French and Swiss-threaded cups for their Quad and Defiant sealed bearing BBs, as well as British-threaded cups for 73mm wide shells. The replacement cups fit on all the described BBs, but SOMA says "If you plan to swap in IRD Italian/French conversion cups, it is more economical to buy the QB-55, than the QB-75.".
Think of it as a modernized version of the Shimano UN-xx bottom brackets with two removable cups, which you can fit with Phil Wood cups to fit your BB threading. https://www.somafabshop.com/shop/product/ird-bottom-bracket-conversion-cups-pair-2839?category=967 https://www.somafabshop.com/shop/product/28819-ird-bottom-bracket-73mm-converter-washer-pair-2538?category=967 Peter Adler Berkeley, CA/USA On Wednesday, October 13, 2021 at 9:42:51 AM UTC-7 eric...@gmail.com wrote: > Installed with cranks, never ridden, zero miles. > > $30 shipped CONUS.
