but the only thing is your shifting ramp will not be in quit the best place.
Yes it will, as all 3 rings will be similarly displaced. Although I don't recall Middleburn rings having ramps?
Ah, I seem to have deleted the part that I was meaning with respect to shifting under/not under power (I had typed it, but must have deleted during editing, don't you love small mobile phones). They are normally designed to shift in the places the load is lowest, or at least Shiamno/Suntour used to be.
No idea if Middleburn SlickShift
is, not looked at their profile on mine.
The 180 turn only 'fully' if the ramps/pins/cuts stay in the same place.
I've never had to worry about it
, though some people made some for this hidden arm setup (Sugino and anyone that rebranded them e.g. Tioga and also TA I think?)
