Parallelogram derailleur 7 Speed Brompton aftermarket mod Not P Line

[bikegang]

#Thx4Ride parallelogram derailleur kit for an old frame (non P Line) to run 7 speed
Stock frame compatible
Stock Wheelset compatible up to 4 cogs (with #MiniMODs yet to release X4UnibodyCogset or X3+1 setup. 5 cogs might be possible)
7 speed in this demo video was on dedicated wheelset
This Kit will include tensioner, parallelogram derailleur and jockey wheels and optional shifter (thumb shifter or XShifter electric one)
Design testing stage

Brombacher had a 4-speed kit for a while, but without the parallelogram. Is the new tensioner as good in gathering chain slack as the original one? Getting stuck with a cassette from one source is not fun. It is a consumable.

Will be testing it soon ... I am more interested in this setup than 7 speed ..
