I don't know how I stumbled into this insinuation that I'm trying to use something bigger than a 28. The big cog on the freewheel I'm trying to use is only 24. The 32 I mentioned is a front chainring. To be honest, I could probably just block off the big chainring and use this as a 42-32 double. I just want to make the full triple work.
It was a 48-34 : 13-28. Yeah I guess when you're done with this experiment you can publish some peer reviewed chain wrap data for the SR RD.
