I moved here 5 years ago - when I first got here everyone was still wearing their fullface DH helmet on Fromme and you would still see 25% of the riders pushing their DH bikes up mountain highway. It seems like over the past 5 years all mountain/enduro bikes have really taken over since they can do 80% of what a DH bike does while still being totally climbable. I don't work in the bike industry or have any sort of inside knowledge, but I've got to imagine that DH bike sales have been decreasing recently.
I agree, and my 'go to' bike is a hardtail for nearly all my riding around here. There's people out there who still want a purpose built thoroughbred rather than (or in addition too) an all-rounder.
For shits and giggles….here's some footage of a trail that I started to build in 2007 (hence getting name after 'me' when finished…) in Cannock Chase, UK which probably has around a 200ft vertical drop at most but people still ride DH bikes on it. No uplift (LOL etc…), just push to the top and repeat.
Anyway, I also agree with Jerry-Rig. How many Endurbro riders to Santa Cruz sponsor? I honestly don't have a clue because the Syndicate DH team get all the publicity. They probably don't sell many V10's, but they sell a bucket load of Bronsons, Nomads etc off the back of their image. And yeah, who wants to watch Enduro coverage? It's definitely a sport that you do rather than watch.
