Bottom is wet, best to do loop out at top.
czajec
Super fun trail, definitely short landings and watch out for the left side optional takeoff on the step up. It’s got some serious pop
ckohlmeier
Trail is very fast for the size of table top. Gotta scrub most of them. Most of the landings are short and it’s easy to huck all the way to flat. Cool floaty step up after the first three rollers.
We hope you've been enjoying Trailforks!
