Look for the entrance of Air Chair next to the entrance of SST
(not to be confused with Golden Spike
). Rideers will start with a brief traverse to a small rock spine, where the pace picks up and the singletrack rolls out in front of you. There are a number of roots in this first section, but they are pretty smooth and not treacherous. There's also a number of in-trail rollers that are fun to pop off of.
The trail will dive down into a drainage just after a small rise between two trees. This section can be sloppy in the winter, but try to keep your speed up to ride up the other side. At the top, the trail crosses over Coyote Ripp
(keep straight). The steepest, and most difficult, section of Air Chair is coming up.
As it heads down the slope, the grade steepens quite a bit, leading riders into a rutted turn followed by a two-foot drop. It's best if you kick your front tire out, and don't plan on rolling it. If that's too much, there's a tight ride-around on the left and the two quickly merge back together to surge ahead on a more level stretch.
Riders will bob and weave through the aspen trees until the singletrack crosses Dos Copas
. It will do so again very shortly, just watch out for a tight squeeze the second time. On the other side of the wide corridor, Air Chair comes to a steep rock roll. It's fairly grippy, but the transition is abrupt and the run-out is on the rough side (scope it first).
Another fast section leads through the trees. Most of it is smooth, but there's a tight set of rough turns to work through. Watch your line selection as it's easy to have your rear tire get kicked around or drive your front tire into a moderate-sized rock.
After that, it's back to smooth trails with a few optional booters along the side. There are three bridges ahead. The first is plenty wide and has a good approach, the second is a narrow plank at the bottom of a descent (be alert here, especially if conditions are wet), and the third is another plank with a fairly gentle approach.
Continue across the powerline trail into the lower, more shaded, section of Air Chair. This is another fun part, with a few small rougher patches as well as off-camber corners. The end of the trail finishes with a walk out of a drainage to reach the road just east of the exit for Back Door
