Juintech have released a flat mount 4-pot caliper. Some notes of interest:
-extended mounting points to eliminate rear brake block
-one piece construction
-75g and $180 per caliper

-available on Aliex and Amazon Prime
These are the lightest, but also nearly the most expensive caliper on the market. It’s a similar concept to the Hope RX4 caliper, but are nearly $50USD more expensive.
Overall interesting to see these brands enter a new era where they are positioning themselves as the premium boutique option.
