We can't think of many people better to test a new bike than Aaron Gwin, so YT must have been champing at the bit to get him on the new Jeffsy 27.

Here's a video of him putting it through its paces both up and down on the trails he calls home. Safe to say, he's taken to it like a duck to water. YT said: "Gwin: Legend. Jeffsy: Legend. You and Us: Legends."
