      Duration Product Used: 1 Year
      Strengths: Great pro pedal feature. Simple dials. Nice volume and good rebound.
      Weaknesses: None really. Mybe the boost valve is hard to get to.
      Bike Setup: Rocky Mountain Slayer SXC70
      Bottom Line: Some people may not be setting this shock up properly as I hear stories about being "stuck down". It is my opinion only that one should never set a DHX Shock based on a persons body weight. I set mine up using the 25% sag rule and it results in more air (psi) in the shock. When it is filled right, the shock is amazing. It really enhances my Rocky Moutain Slayer. This is a large high volume chamber, so the body weight rule may not work.

      Bottom Line..............good shock for over a year.

      Duration Product Used: 3 months
      Price Paid: $2
      Strengths: Good shock, nicely adjustable, takes everything i can throw at it, platform works well
      Weaknesses: My shock pump is a bit hard to maneuver into the boost valve, but that's the pump, not the shock. Takes a while to get dialed in correctly.
      Similar Products Tried: Vanilla R
      Bike Setup: Norco Six 1 '07, stock except for Syncros BHT tyres and Wellgo pedals (just didn't like the DMR V8's)
      Bottom Line: Well, it seems that MTBR has a bad case of the "only review it 'cos it broke" going on. My shock has been fine, i stuffed it up by putting the shock pump on too hard to the main reservoir, but it was a $5 fix for some new valve cores and a core tool, now perfect. It takes a bit of riding to get the sag, rebound and bottom out (boost valve) set, but once you have, it takes everything you can throw at it and more. The lack of "bottom out" control doesn't matter since the boost valve does the same thing - just run the shock with 175psi in the boost valve and it will eat everything without bottoming out. Propedal seems to work quite well too - with 175psi in the boost valve, even standing and mashing the pedals hardly bobs at all.

      Duration Product Used: Less than 1 month
      Purchased At: United Cycle
      Strengths: Propedal works well you can limit the peddle bob with this ajustment.
      Weaknesses: I am disapointed with this product. First time ever I buy an expensive bike. Assumed that all components would work flawless. Mistake the shock id leaking oil from the rebound adjust button, the dealer supposedly sent it back to get rebuilt but the didn't fix the problem. Can you guess the shock is still leaking and from the same location. You would think that if you bought a high end bike the store or manufacturer would go out of their way to make sure all components work probably before selling them. Save your money and buy a Walmart throw away, you'll be happier you did!!
      Bottom Line: Crappy rear end on an expensive bike. And After being rebuilt to repair the leak the bike shock still leaks. I wonder, did it really get rebuilt??

      Duration Product Used: 1 Year
      Purchased At: came on the bike.
      Strengths: ummmm........ nice colour????? Sorry, that's all I could come up with.
      Weaknesses: I just got the bike back from a warranty job on the shock because it stuck down. I guess I have about 4 or 5 rides in now since I got it back and it happened again. I was 25 km's out and had to gingerly ride it back so I didn't rip my tire to shreds or pull off the front derailer. (Enduro riders will relate) I was pissed. I'm sending it back but this will be another 2-3 weeks off of riding because of this useless piece of junk.
      Thats twice in less then 5 months of riding.
      Similar Products Tried: My walmart bike with the rear suspension lasted years longer then this thing has.
      Bottom Line:
      Bottom line? Garbage. I hope someone from Fox reads the reviews on this model and notices the theme. If you're buying an enduro ask them to switch it out to something else. Spring perhaps?

      I don't grunt up a mountain on this pogo stick of a shock, with its negligible propedal action, to waste one of my two measly days off per week, to do 20 metres of the best cross country trail in Nelson BC (Paper bag for those interested), only to have my recently rebuilt shock break down AGAIN.
      Sorry folks, I just got home from this and I'm fired up.

      FavoriteTrail: fisher creek
      Duration Product Used: 3 months
      Purchased At: came on specialized enduro
      Strengths: fox product,
      Weaknesses: heavy, useless piggy back reservoir. leaks oil out out adjustment knob.
      Similar Products Tried: fox float rl (it was flawless for 5 years)
      Bike Setup: enduro elite
      Bottom Line: ive had the bike two months and its never been on dirt. (its middle of winter) i ride it to work and back daily. (about a mile on pavement). apparently from my bodyweight alone, the shock compressed and stuck. it would not return. i thought it was just low on air, but that wasnt it. the bike shop said it blew an internal seal. how, i dont know. if this is fox's finest free ride, dh shock, they need to go back to the drawing board. i am already looking at other options (rock shox pearl). the plus is, fox is good about repairing the shock, but im guessing it will be broke again after my first ride. maybe just a lemon. i will write another review in a couple months

      FavoriteTrail: Monarch Crest, Colorado Trail
      Duration Product Used: Less than 1 month
      Strengths: Looks Nice
      Weaknesses: Leaking oil on the first ride. Nothing major as far as hits. Leaking out of the rebound adjustment. New bike from Rocky Mountain. 2 week wait from Fox so they can rebuild the piece of crap.
      Similar Products Tried: Came on the bike.
      Bike Setup: Talus 36 on the front xt, jucy 5, race face, mavic
      Bottom Line: Nice piece of crap. Its good to know that I will probably need service on this shock again in the near future. Fox will not be a consideration in the future if they send out product like this. The shock was setup before the first ride. Sag, pro pedal etc.

      Purchased At: LBS
      Strengths: It is smooth when they work.
      Weaknesses: It stuck on the fourth ride.
      Similar Products Tried: RockShox Sid. Never a problem
      Bike Setup: This shock came on my 06 Enduro.
      Bottom Line: After only four rides on the bike the shock stuck. I had to have it rebuilt. I am not sure how it will do on the long haul but one would think it would have held up better than four rides. The rides were XC trails nothing extreme. I am thinking for this type of bike a coil shock may be they way to go. If the shock goes again I will be replacing it with something else, not a Fox.
