While rehabbing I sent my Fox Float 32, 100mm fork sent into Push (thanks @qcanoe) for a rebuild and the addition of a High Volume Air Piston Kit for my Trek Superfly 100AL.
I also had them extend the travel to 110.
I am not an expert but I do have a good feeling for how my bike feels and works. I was not happy with the OEM fork; it felt sluggish, dead and had really poor small bump performance. An example is going over small rocks and roots (say 6") and the fork just feels mushy and slow to respond making the bike handle slow. I had played around with air pressure and rebound but it just didn't work well.
Push made the whole process simple. Just register and pay online, fill out a form with your riding style and likes and dislikes of the fork and mail the fork in. Push sent a e-mail letting me know they received the fork and a few days later, it was in the mail.
The fork came back looking new with stickers and a service card showing the optimal settings.
I took the bike up "Spring Creek" which is a 5.2,(10.4 r/t) ~1500' climb from downtown to Buff' pass. Its not a technical ride but a really scenic trail that meanders along and cross's the Spring creek as it ascends through a canyon. A great mixture of flowy single track with some loose rocky stuff and some fairly steep pushes through aspens, evergreens and tall lush ferns. A good amount of shade too. It's busy trail so weekdays are best. Since its all up hill; the down is a lot of fun! I was riding with @gregmerz and we had a great ride although Greg was still suffering from "flat-lander-fever" AKA, no O2... but he did a great job.
So, back to the fork. It didn't take long to really notice a huge difference. entering the trail is a jeep road with a few rocks and potholes. I rode over them to see if I could notice any difference. The PUSH fork was noticeably more compliant and reactive. It made riding over this kind to terrain so much smoother and less "disruptive" to the ride. At the end of the road, the trail climbs steeply with loose rocks and sand, and switches back. (the guy coming down in front of us dumped it) This was the first test of the fork, climbing while taking small rocks. The fork stayed stuck tot he ground making it easier to navigate, get traction and climb. Excellent small bump compliance/performance! The fork had that exact feeling of stability precision and confidence I was after.
As we ascended the trail, there are a few rock gardens on steeper climbs. Again the fork really made this terrain much more compliant. I felt more confident with my bike handling and took more aggressive lines.
After reaching the top and taking a bit of a rest. The fun part comes... 1500' of descent! I dropped my seat post and headed down. The fork really shined on the down. with the extra travel and the super feel, I was riding faster than before taking the turns and switchbacks with much more confidence. The bike was smooth, predictive and stable; stayed glued to the trail.
So, I highly recommend that if you have a Fox float to ship yours in for a rebuild. I am sending in my rear shock this fall.
