    SX trail issue

    I am looking at purchasing a 06 sx trail, I am pretty much obligated now since I borrowed it from the local shop for the weekend(whole nother story). Anyways, I was curious about the dhx 4.0 on the enduro frame, I notice there is no boost valve on these frames. It appears there is a valve and threading, as if you could us a 90 degree adapter or something. I am just curious because this bike rips and pedals well with the propedal, and am just worried about have adequate air without having control and adjustability, this means that this is Not a 4way adjustable shock. I hear that the propedal won't even work with less than 100 lbs of air, and I don't even know how much air is in there, plus it seems rear shocks will leak at times, what do you do about a shock that you can't adjust the air? What's up, and who makes some nice shocks for this setup with a resevoir, not piggy back or atleast one with the valve where I could acess it on the enduro? Any info will help, hope you can make sense of above.
    Thanks in advance.

    If I remember correctly, Specialized had all the DHX 4.0 shocks they bought specifically valved for their bikes. They felt there is not a need for a 5.0 on that bike. I could be wrong (if I am, somebody correct me), but I remember reading that in MBA or Decline or something.

    There is no boost valve adjustment, how would you know what the "standard" air pressure is? The 4.0 is supposed to have the shrader valve, but not on the enduro. It rides really nice and the propedal works well. It seems without the air adjustment there's a lack of adjustability. What are some shocks that have the resevoir? Will it be a good setup with this shock on the sx? It rides real nice and the propedal works well as mentioned before. Anyone heard about these issues with sx's, it looks like there is a valve, not schrader, that should might be able to get an adapter, there is threading and a valve. I will contact Specialized and Fox racing.
    I still do not see why a 5.0 would matter. The Enduro frame is in the way of any air adjustment with a piggy back, and lacks the adjustable air platform, what's the deal?

    No DHX 5.0 because it dosen't fit the Enduro SEnduro was built around the 5th Element air shock they didn't allow for shocks that had boost valves, if you tried one you would have to remove the actual air valve , I know of one ride that the guy dosen't get yr ride desciption and is bummed he can't get a plusher ride in his case the valving hasn't worked for him oh well, the chain line sucks as well otherwise its a nice ride, oh he knows his stuff no one can fix his problem maybe a different shock if the i2i could work as thats another problem.

    My shop is giving me a deal on an 05 SX with a Marz 06 66VF2 for $2300.00.

    This has me worried since I was looking to upgrade to a Romic.

    Romics were nice in there day, I don't think theyve done much for atleast a couple of years correct me if Im wrong.

    I'd maybe look at a Marzocchi Roco if the i2i and stoke options fit then this should suit the SX trail very nicely, also look at some RF cranks the best option for a Specialised to get yr chain line as sweet as possible. Just make sure you are getting the 06 66, the 05 will be way too long in the A2C for the SX 06 will be fine its 40mm less a2c.

    Enjoy its a nice bike once the bugs are sorted

    I just had a look at the 2006 Specialized website which shows the DHX 5.0 coil-over on the SX Trail II and DHX 5.0 air on the Enduro Expert.

    Go to the Specialized forum and look for the thread about '05 Enduro Coil Shock options. There's pages of discussions on this. I would stay away from the '05 because your choice of shocks is very limited. Some have gotten aftermarket DHX 5.0 to fit but you have to unbolt the shock to get to the air valve and there is some contact on full compression with the '05 SX Trail because the stroke is 1/4" longer than stock. You can also send the stock shock to Fox to adjust the air pressure however you like (I had the same concerns about leaks and no-adjustability). You can get a Cane Creek and Avalanche to fit but they are crazy expensive. Romic will make a custom length shock to fit but not sure if it will perform as well as the DHX, Cane Creek or Avalanche.

    My '06 SX Trail II came with a DHX 5.0. The air valve was removed so it could fit the frame I believe.

    I went to the local Specialized dealer to finish up payment with the sx today. They are going to contact fox and we are just going to add the air valve so that I can atleast remove one mounting point and slide the shock to adjust the air. I heard fox makes a dhx with a remote resevoir, anyone heard of these?

    I would upgrade the VF2 fork before worrying about the shock.

    Fox does make remote DHX's, but they are all OEM from my understanding. Turner DHR's run them, but I didn't have any luck getting one for my Demo.
