My daughter has Hope tech 3 brakes on her DH bike. We have some Hope tech evo brakes on an xc bike. Both levers have adjustable reach and BPC. Can i take the tech evo levers as spares for our alpine trip? To fit the tech 3 v4 brakes on the DH bike?

I would just ring hope technical support. They are brilliant to talk to and know hope stuff inside out as you would expect. 0 1282 818413

Yes, they are interchangeable. Biggest concern would be if they could push enough fluid for the v4 but both have been specced with that caliper so you’re fine.
