Duncan, I used one on a half step 32-48-54 on a Tandem. If was more than needed but it worked (only halfstep)
They made a narrow range double unit that would not do this but I think it was label cyclone II. The really old unit was also probably a double but the cage was a little longer.
No warranty on this advice.
