It’s called The Grinder for a reason Do some challenging climbing early on and get into the grind. The higher elevation black section of the trail is very different from the blue section. The black segments are narrow and often steep, while the blue is more rolling technical terrain. This route has you go up Horsefly, which is very steep. Expect to push your bike uphill for a bit, unless you have excellent fitness!

Trail The Grinder
Don’t need suspension. Better on a gravel bike

Trail The Grinder
The Grinder is definitely fun. Appropriately named though since there are many punchy climbs, but downhill sections have decent banked turns. Went clockwise.

The beginning of the trail is full of downed trees and is just a torn up old road. Then all of the sudden turns into perfect singletrack. Very steep though, we were pushing most of the way up to grinder. Seems like a weird way to get to one of the best trails in the area. (Mineshaft)

West of FS 189 is in great shape. A couple down trees but easily bypassed.
