Can't rightly remember what year this frame is, but I think it's at least 20 years old now. I gave it a major facelift in 2020, and a few minor ones since then. Relatively modern geo now, plus it can fit 29 x 2.8" or 27.5 x 3.8".
I run the skinnies in the spring when the snow is gone and there's still moisture left in the soil.
I run the fatties the rest of the year -- high summer when things are blown out and moondusty, fall when the roots get wet, stripped, and slick, and winter with studs.
For '23 I had a buddy modify a set of Revelate Nano Panniers to fit the custom rack. It's a bikepacking rig par excellence, and it has deserved custom bags for years now.
