>>1733529>can I get a qrd on the difference between them? I thought the terms were interchangeableMy bad, they are all shift triggers due to the prefix Being ST
it an force of habit of mine to call the newer ones as shift triggers because the marketing for "rapid fire" became less overt over time
older RapidFire levers have the cable tension release actuated by the thumb (ST-M090 (1990)
slightly newer RapidFire + levers have the tension release actuated by the index finger (ST-M900 (1992)
1996 brings RapidFire SL Trigger shifters, a major improvement, but still slightly fragile
the most reliable and easy to fix type I have seen are ST-EF20
ST EF-29 (EZ-FIRE) is also very good mechanically, but its viewing window thing is not uv stable and goes yellow and cracks over time letting water in
modern cheepo ST are more like the EF-29 but the action is not so smooth and the surfaces less well finished, personal preference
a problem I have run into is that many newer ST are for V brake or if they are a cantilever version only have 2 or 2.5 finger length
the 3 and 4 finger ST levers are slightly less common, and the lever length is not implicit in their product code more of a foot note in most documents
>BR M201low profile type best paired with 3 finger lever, not really a favourite geometry of mine, I've broken a few straddle wires and hand levers of this kind of brake
medium profile cantilevers are for sure a nicer experience, I read in some old MTB magazines that 4 finger levers are used to "reduce hand fatigue on long decent"
but shorter hand levers are fine if you have rest of the brakes set up perfectly
>any recs for tried and true of that style?I cant really recommend anything in the Rapid Fire or Rapid Fire + range, hard to find in good condition
and their Rachet and Pawl mechanism is very compact on old such old models (same problem as most Brifters iirc)
