    How much of rear flex is due to rear wheel?

    I have some Arches on my bike now and am starting to hit bigger jumps, drops and more tech. The rear seems pretty flexy so I'm considering putting a new hoop on it.

    Will it make a big difference in feel and stiffness?

    Any recommendations? I'm hoping to not spend a lot since it's non-boost.

    Depends on the make/model of frame and the wheel. Stan's arch's are a bit flexy but not as bad as some. You won't notice much difference going to another aluminum wheel in my opinion. You'll get maybe 10-15% subjective improvement in stiffness. Much of the stiffness concerns we have in full suspension bikes have much more to do with teh frame then the wheelset however.

    I agree with minimusprime... hard to say without first hand testing.

    A couple of thoughts...

    Stans rims can be a little fiddly. I have built some Crests... super light, but very flexy.
    Their rims tend to be sensitive to tires and pressures... I would check your spoke tensions... tension could have gone South in the wheel. I highly recommend final tensioning of Stans rims with tire mounted and aired up to pressure.

    If you rebuild, I would consider upping the spoke count. I generally go straight to 32 for off-road work. It doesn't really add much weight, but it really helps strength and stiffness. (I know this might mean a new hub too, but worth it)

    Thanks for the replies.

    Currently have 32 spokes. The bike is a BMC speedfox. I'm first going to replace the linkage as I'm getting some creak and it's been a while since I replaced it.
