I’ve not ridden the enduro evo, but I have ridden the air sprung new enduro and the 2005/2006 enduro.
New Enduro rides very similar to old enduro, but is slightly lighter (maybe the evo wont be due to the coils?), therefore in my opinion is better. Goes downhill just as well, climbs better because of less wegiht. Seems easier to lift the front wheel on new enduro (shorter chainstays?). new enduro seems a bit longer in wheelbase, and slacker in head angle, so handling is changed accordingly. The old enduro could be a bit of a handful on a tight twisting trail, so I’d imagine the new one is a bit worse in this respect.
Size wise , the new enduro in medium feels more cramped than the old enduro in medium.
