A fun descent with small rock slabs scattered along the trail. But can also be used as a steep technical climb, the most efficient climbing route to the top of the hill. You'll be pushing your bike in several sections unless you're a super hero with trials skills.

An under-appreciated gem of slow, techy, rock rolls, with lots of options to spice it up. I usually just push up the same decent line and finish by heading right (West) on Summers Eve until it connects to Silver Spoon, which isnt necessarily much more difficult than Phlegm. (Features have alternatives) Five stars.

When descending this (almost) always take the right fork when presented with the option, and you end up with a great ride with lots of rock slabs. Finish with Golden Years.
We hope you've been enjoying Trailforks!
