I have a ISCG 05 Blackspire stinger, I'm soon to be purchasing a frame that doesn't have ISCG mounts so I'll need to be mounting a chain device via the BB.
What is generally the difference between an ISCG chain device and a BB mount one? Obviously the lack of ISCG tabs before anyone goes there
Can I just use the ISCG mount sandwiched between the external cup and the shell like you would? Also will most BB to ISCG converter things work with most chainguides or do they all differ slightly?
