Received the 104BCD spiders I needed to reverse-engineer the 8-bolt interface for.
Made this spider to work with a SRAM T-Type crank to provide a 55mm chainline/beltline suitable for use with Rohloff hubs (their standard QR model has a 55mm belt line as standard).
I’m pretty happy with the fit.
It’s quite disturbing that the standard SRAM fit is so sloppy.
