I have to repair a Shimano STX shifter 7 speed (from a Raleigh MT200 bike from 1995). It has a broken spring, and I am almost sure that is the only thing to be repaired.
It is similar to that pictured in https://www.cs.hmc.edu/~geoff/deoredx/reductions/P2004.09.08-10.17.55-3814-labeled.02.html
I found a disassembly of the brifter ST-EF28-Left. In this figure, the broken spring would be "Coil spring", I guess.
I would be happy to get a minimally invasive solution.
Is there any chance of getting the replacement part? Where from?
Otherwise, I would get a new shifter/brake, only right side. I found several options. Can anyone let me know which is the order from lower end to higher end?
- Acera SL-M310
- ST-EF28 (my spring is similar to the "Coil spring") here
- STX (from ebay, e.g.)
- Some V-brake option (see Shimano integrated shifter/brake: Cantilever compatible with V-Brake?)
- Some other 8 speed option (it is ok, as per links below).
