NEMBA's new machine built flow trail in homage to Earl and friends for gifting the community with this legacy of great trails. Double E (Earls Evolution) signifies a committed effort by NEMBA to revitalize the network onto a modern sustainable and accessible trail system for all levels of riders.
Trail features a series of progressive rollers, berms and jumps to allow the green rider to safely build skills and begin to push their skills into the blue features. Expect primarily slow flow with playful features through out. With any trail that has progressive features please remember to Pre-ride, Re-ride and Free-ride as you become familiar with the trail.

Great trail! The doubles are perfect for pumping or gaping. Berms are very solid and well shaped. The jumps are well made with good landings. I wish it were longer!
We hope you've been enjoying Trailforks!
