Downhill bike setup question

I recently bought a SX trail frame for my riding needs. I do mostly downhill and was contemplating the idea of trading out my 36 talas for a triple clamp 7" fork such as a super T or a 7" 888. How many of you think this would be a good idea or would this make the bike ride uncomfortably.

Remember keep in mind I do mostly DH riding. I have seen a few pictures here of people riding the bike with a triple so if those people could give me advise thanks. No I will not just go with a 66 and call it done. I have a 36 150mm and the upgrade or downgrade to a 66 is not something I am thinking of doing.

Thank you. and once again would a triple on the SX trail make for a bad and uncomfortable DH ride bike.


If you are wondering this is the specs I'm running now.

My gut reaction is that it would make the bike ride poorly because it would slacken the head angle too much and raise the handlebars too high. Keep in mind that the bike is designed around the new crop of 6" or 7" travel single crowns, which generally have lower axle-to-crown heights than triple clamp forks.

I agree with dexterq, putting on a 7" triple is most likely going to make the bike a bit too slack (if it has a higher a-c height). Which will take away the advantages of the frame you have, which is nible and very responsive. You really should be looking at another frame if youre mostly doing DH.

Personally Id leave the setup you have atm, that bike rips the way it is right now. Use the advantages the bike has right now rather then trying to compromise it into a full blown DH rig.

Holy bar height bat man. You should get a 66 if you want a DH fork, either the RC2X or the SL. I would go for a 7" 66 RC2X.

Wow, harsh words. Here's my 2c.

What is the stock HA on that bike? 68? Just a guess considering it's intended use as a all-mountain/freeride bike. Now, 68 is a bit steep for DH so going from a 6" fork to a 7" fork with a slightly higher axle-to-crown would slacken you HA between 1-2 degrees making it PERFECT for DH. Now, it would also raise the BB a smidge, but I think it wouldn't be that noticable.
That bike is perfect for recreational DH. You won't win a world cup on it, but 6" of travel with a really good shock like a DHX is plenty.

If you wanted it to be more of a dher, the best thing to do (in my opinion) would be to put a 66 on it. It is a nice do-most-everything setup right now though.

boxxer ride a option?

That would actually be a great DC option, plus you can find them used for pretty cheap and they've got 5-7" of travel so you can still climb with it.

[SPAM]I've got one for sale cheap, PM me[/SPAM]

The HA of that frame is 66.5 and 67.5 depending on which shock shuttle attachment you use when a fork such as the 36 van r is used!

This frame is rated up to 175mm of fork travel. I am not sure if a-c is the issue or not. I don't really understand it, but I think the travel of the fork is more important in voiding the warranty than the a-c height!\\

One thing I will ask, where do you feel the bike/set-up is lacking? Or was this just a question to see what others have felt?

All that said, I think with a heavy set of rubber/tubes, a 10mm rear axle, some 8" rotors and a 66rc2x 170/ 170 fox 40 would kill on that bike. Even a 7" boxxer:)
The only reason I did not keep miy sx trail II is because I wanted a bit more travel to handle the ruts and roots better in races. Slightly more travel is going to help you keep from skittering all over on those roots and rocks...This is not to say the sx cannot handle it!!! My opinion was that I am not a super smooth rider and after a year and a bunch of pivot/bearing replacements and root gardens/washboards in the DH races around here, my body would kill me. This environment will put a lot of additional stress on a bike (and you) that is mostly meant for heavy trail riding.
So I clawed together as much money as I could to try and get a slightly bigger rig! I got the intense uzzi instead.

If I were you, and not really interested in racing or anything I would get some big tires, heavy tubes, a used boxxer world cup and some heavy duty brakes! If you break that bike in this set-up you know youare ready to move up :)
I wasn't worried about breaking the bike, I was worried about breaking me!

Good luck

Hey i got some Hope mono ^ tis from X-vert. Great powerful 205mm brakes.

I thinking of getting a 7 inch fork but i may just wait till the upgrade to come out for my fork, t0 160mm of travel form 170mm. This should help a little.

I have one question, why put heavy tubes in it? I have it weighted at just under 37 pounds.

im sorrey they did not add 2-3 pounds they might of added like a pound at most. But the stoping power is increadable. I can really pic up speed and not have to worrey till the last few seconds to hite the brakes.

Yes it can handle a 175mm triple clamp fork such as a super t and still be under warrenty.
Oh, I was thinking of the Enduro earlier. Sorry for the confusion.

But i thought a lot of Dh try to get thier bike light. Would heavier tubes stabalize the bike better?

Do it if you want to void your warranty...
I'll second that. A guy I work with wants to buy a sx trail and put a dual crown on it and our Spec rep said it would void the warranty.

Putting a DC fork on defeats the purpose of the bike. It's meant to be a lighter FR bike, to use with singlecrowns. If you wanted a DH bike, you should have gotten one.

The 66rc2x's are really nice. I rode my freind's as-x with on for a few hours. Its a very nice fork. You won't be disapointed if you get it.

its more of a convenience thing, for the avg rider the extra weight of the tubes is negligible compared to being more susceptible to getting flats on rooty, rocky trails.

The only reason pros use normal tubes is cause their lighter, and for them every little bit of weight taken off their bike helps

well i havn't gotten flat spots for over 4 months and i run low psi on reg tires so, does the extra weight actualy help stabalize your bike on the Dh course?
