Are these shifters worth the effort to make work? Are there other shifters (not expensive) that do the job better?
What about adding a brazeon? Is that hard to do?
Without that Nubbin on the downtube just about any shifter can slide like this....the problem is compounded by the fact you're using these Cyclone shifters. I had a helluva time getting mine tight enough, and even then I didn't think they were all that great. I ended up ditching them after a week and went with bar ends.
You dont wanna add a brazeon. You'll wreck the paint.
One workaround you could do that would stop the slippage for sure is to install the shifters above the pump peg. The pump peg will prevent them from slipping down
