I rode my Rockshox Lyrik RC2 DH Solo Air for all of last season. I love to catch air and tackle technical terrain, and took everyopportunity to hit lots of both while tuning in the damping.
I did a lot of playing around with setting on this fork, which thankfully is made easier by the little turtle and jack-alope icons. Maybe it's just the way I think, but I found Rockshox's tuning tips to be of little help, so it took me quite a while to find my settings. Once I found my settings however, I felt a lot more comfortable on the bike.
The one thing that i couldn't overcome was the slightly sticky feeling on the rough terrain. On big hits the fork was wonderful and never bottomed out, but the fork felt sluggish in rock gardens, no matter how few clicks I ran the damping.
Overall, this is a good fork that surprised me on it's big hit capabilities, but left me feeling compromised on rough terrain.
