One of their employees used to race DH (might still do) and was happily informing people that it performed better with the chain off
My Stage 6 feels amazing with the chain off, I once did an afternoon of chainless runs at Gwydir when I had freehub issues. Definitely felt plusher and less hang-uppy than usual. And it doesn’t hang up on stuff much anyway.
Haven’t tried any other bikes chainless to such an extent, maybe I should though.
I wonder how much the Orange stiffening-under-braking thing would really bother a WC racer, as they’re riding with a level of commitment (and a lack of braking) that the rest of us can only dream of.
