I used to have the rebound set full to the slowest position on my Rock Shox Reba SL, but I started riding more aggressively so I loosened it up with a few turns which felt good just pushing down on the bar. On the ride, it felt a bit too pogo-stick like. I later discovered, while I was riding through rough rocky downhill sections and after got a flat, that the knob was totally gone when I flipped over the bike. I'm guessing that it's not secured on and is like a valve cap? Can I get a new one anywhere cheap and convenient? Is there any elegant way I can secure the new one, so I can adjust rebound to be faster and not risk losing it again (I'm thinking about just simply taping it).

Also, I'm guessing 30 psi is too low up front with a Reba SL for rocky descents on a hard tail? I tried to patch the tube and noticed it was a "side snake bite", the lower inside with a massive slit (1cm almost) and the upper tire side about half of that size. I determined that the tube got smushed so hard on one side of the rim that it flattened out like that and the force between the rock, tire, and rim sliced through both layers. It was an immediate flat and it was really hard to determine the source of the leak with a portable pump since the air leaked out immediately upon pumping. First time I ever got that kind of flat, but I was experimenting with lower pressure. I used to run up to 40psi up front.

Since nobody has answered you in over 24 hours, I guess I will. The rebound adjustment knob just pushes in on the bottom of the fork. It almost snaps in so it should never pop out while riding. You might have accidentally loosened it while playing with it. Any bike shop should be able to get you a new one. There is a correct setting for rebound travel, if unsure, ask your shop as well. It should be set where it come just short of full rebound after "snatching" the front tire up.

Your flat is what is commonly called a "pinch flat". Comes from running too low a pressure or the tire taking a big impact. 30psi is too low for a tubed tire. 33-34 is about as low as you can comfortably go in normal conditions. Add rocky conditions and that needs to go up a couple psi. Tubeless tires can go lower without problems in these conditions, that's why so many DH/AM riders use tubeless set-ups.

Good luck.

if the reba is like tora a 2.5mm (i think) allen key can be used to adjust the rebound. in a pinch the rebound adjuster can be used as an allen key. Based on finding a rebound adjuster on the trail I figure it is wish to keep a spare
