2nd Generation Mountech
The2nd iteration of the Suntour Mountech RD. Where the first version had a captive, spring loaded upper jockey pulley- the 2nd version put in a normal upper jockey pulley, then it also had the 3 pivots (the Dual Parallelogram), and also a 13 tooth lower pulley.
I think the triple pivot design is a solution to a problem that didn't exist.
On the other hand Suntour's triple pulley derailleurs were fantastic.
