a real longshot but anybody taken a SRAM rear mech apart - I refer to 11 speed x01 or xx1.
the 4 pivot pins holding the parallelogram together have clips on the ends so it looks like it can be taken apart quite easily -so what size is the spring : outer diameter, wire diameter and length (and SRAM do not sell the spring separately)
