interesting development:

seems like Mango is expanding but the value doesn't seem to be there with the new bike.

the had a Nexus 3-speed option (which was there for only a few months)
now they have a 18spd Microshift option which seems not so cool for the money (449 GBP)

Mango Bikes 18spd Black Series Matte Green Road Bike - Mango Bikes

i think my bike was right at the sweet spot
