I have tried mine in a few different builds but have settled on a Sektor solo air at 140 and a reverb. Running 34/22 with 9 speed out back. Minions at both ends too (heavy but punture resistant)
I was running fox 36 van at 160mm which was really stable on the downs but wouldn’t turn in singletrack, even getting as much weight as possble on the front wheel with renthal bars and 60mm stem I washed out the front too often.
I have used a Thompson seatpost before the reverb as more comfort comes from the tyre pressures than seatpost or saddle (IMO)
Have fun (the faster you ride it, the better they feel!)
