Thanks, ill keep an eye out for extreme angles. Would be so nice to be able to set it up without issue
If it helps your confidence, I have a 10 speed SRAM X9 set up, including twist shifters, on my 1990 Roberts White Spider, and all I needed to do was tweak the B screw a half a turn, as the jockey wheel was touching the cassette. After that, I did 30K off road in the Forest of Dean.
I haven't ridden the RSP yet, as I managed to dislocate my shoulder just as I finished it
I can't believe the Kona didn't sell... perhaps you are meant
to keep it
