Next level conditions, loads of traction, trail drains well

Super fun trail, little bit of everything and great hard pack traction

Of the three main trails Undertow is the most difficult. Then the Grudge and Hummingbird is last on the list...

By far the hardest of the three trails off rocky peak road. A few rock rolls on this one are quite technically challenge, definitely not let go and hang on like you can do on some on the grudge. If you're an advanced rider and want a challenge this is it, unless you're really good it'll take a couple of rides through to clean the trail top to bottom

I would definitely rate this a double black. Has some ride arounds but a couple features makes this a double black. Best trail I’ve ridden in LA so far for downhill/enduro
