No, the rc40’s have travel adjust. RC41’s have the launch control, which means if you knock in the adjuster, they pack down to about 30mm into travel and lock there, until you hit an adjustable impact threshold, where the floodgate opens and forks become active again.
I love them, best forks ive owned, but i do understand some people dont. I think they track the ground very well, great grip, but (at least mine) they are a little harsh through small stuff.All imo obviously.
I bought some rc40s for my blur classic, but decided against them and stuck with my minutes, thought the longer travel may upset it.
