The rebuilt one is double black and blue. Not black. I'll correct the trails.
tfornelius
This was recently torn down and completely rebuilt. It’s now a wider trail with two lines - one blue and one black (possibly double). It’s smooth and full of jumps and berms
We hope you've been enjoying Trailforks!
