I run Hope Tech 3 levers on both bikes, X2 (dual piston) on my HT and E4 (quad piston) calipers on the FS.
Did Afan, the Wall, and BPW this weekend on the FS and at no time did I feel the need for better brakes and most importantly (for me) did I at any time feel like they’d let me down. Good to have confidence when trying a BPW red/black for the first time!
I think most of the brakes are now very similar in performance but it’s mostly down to budget and preference. I’ve had the X2s on 3 bikes now over 5 years and done very minimal maintenance so for the cost that seems reasonable.
Agree on the colours as I always just go with black!
