    Fork issues

    I'm posting this here because I know a lot of you guys have Pikes on your XCLs.

    I cheaped out and got a 2006 Manitou Nixon Super Intrinsic for my XCL. I tried to ride the bike this weekend but this fork is giving me fits. There was a tag on the fork suggesting 1/2 my weight for the pressure. At 170 psi (which is more than 1/2 my weight) I was getting something like 4 inches of sag. I farted around with the thing and eventually got to just under 250 psi, at which point I still had about 3 inches of sag (I do not weigh 500 pounds). Basically it felt like the thing was bottoming out as soon as I got on the bike. I tried to ride it that way but it just didn't feel right and I ended up cutting the ride short.

    Do Pikes feel like this also? Or is this a Manitou thing?

    The previous suspension fork that I had was a coil Fox Vanilla R 130, which I basically put a heavy spring in and forgot.

    Something does not sound right. When you add air and remove the pump are you loosing a lot of air? Reattach the pump and check what the pressure is. It should be close (less than 5 lbs off). If it is much less, check the valve stem. I have noticed a lot of Manitou forks with a bad valve stems - either too short or too long. Easy to fix.

    No, nothing like that. The pressure stays pretty much the same.

    I also posted this in the shocks forum, and I had someone reply that it could be the intrinsic damper needing service, so I'm going to look into that.

    My Pike 454 is and has been perfect w/out any real headaches for over 1.5 years. It is a dual air and has never leaked. I weigh 230 and I run mine about 150 Lbs in the positive and 150 in the negative. Sounds like your Manitou has issues!

    Yeah, it sounds like it's a problem with the fork. I had a Manitou Minute on my last bike and had no problem achieving the correct sag. You should either get your Nixon checked out or just get yourself a Pike.

    Apparently there's a spring in there for the initial travel that I'm probably blowing through. Not sure it's going to still be available though... I think this fork is from before they were acquired by Hayes.

    I may end up with a Pike... I can only take so much of this forking around (haha!)
