Ddmonkey – just got back from 1st ride on enduro with the crossmax st’s, they are noticablaby quicker and faster rolling than the flow/pro2’s, pedalling up felt easier as did rolling on flatter sections.
But.. I did notice the grip difference due to the tyre profile being narrower. Not a big difference but non the less not quite as good. St’s feel just as stiff as the flows, so no noticeable difference with tracking-holding a line.
So suppose it all depends on what riding you plan to cover with them. I’ll be keeping the crossmax st’s on for trail centre bashing and long Xc rides and putting the flows on for uplift days and alps trips.
For gravity enduro racing…. I think I’ll use the st’s.
Hope this helps.
