There is an internal wheel that is spring loaded against the pull of the derailleur spring but ratchets via friction only in the opposite direction. That is, when you pull against a derailleur spring, the device ratchets and the resistance is friction only, but when you are moving the cable "with" the derailleur spring, the ratchets catch the internal spring loaded wheel and add additional resistance against slippage.
Simplex's retrofrictions (IMO, even better than the SunTour system in the Silvers) is even nicer feeling, tho' that may be due to the small shifter barrels. And my right side Silver doesn't do this. Would like help in troubleshooting or a not-too-expensive replacement. ______________________________ On Fri, Mar 8, 2013 at 9:30 AM, Michael <john11.2...@gmail.com> wrote: > Looks like a mini-ratchetting system.
