I’ve used loads of Formula brakes over the past few years – Oro, Bianca, Mega, One, and a few others I can’t remember…
They seem to get amazing write-upa and reviews, but my experience has been far from rosey. I’ve finally given up on them.
Shimano – XT (best brake I’ve ever used), Saints – 4 pot callipers FFS! They are the best DH brake I would say. XT’s 200/180 would be pretty close too, if not get the better of the Saints
