That still looks like a de-tensioned wheel issue. I can see equal amounts of swingarm and linkage on either side of the tobe tube, seat tube line

k, so your saying it would flex that much AND flex back?
i know all materials flex a certain amount, but to flex that much and flex back is pretty amazing

Yes, it would flex back.
Youngs modulus shows that a materiel will flex, and return back to its original shape as long as it has not gone past its "yield point", or the point of permanent transformation.

If you consider how long the whole swing arm that is flexing is, the amount of flex per inch of material would be relatively small.

If you think that that is a swing arm flexing, then A: you have never rode a Rocky Mountain RM6 or any of the thrust link DH bikes, and B: you need to step away from the computer and ride your bike and just stop comming here. This is rediculous

i know that, but to the extent that stryks talkign about seems stupid, over half an inch and back? and with aluminiun that knows to be stiff as f*ck

I agree that it is very likely a badly tensioned wheel, or just as shitty wheel, im just saying that i think it could be possible within the materials capabilities to do what he is saying....maybe not though...

Yes the RM12...6" of vertical travel nad 6" of lateral flex...the rear wheel actually stay upright in corners when the rest of the bike was tipped over...not really swingarm flex more like main swingarm yoke flex.

people lived in denial due to the intense sticker.Facepalm


wathed a few videos of dh racers and its mostly single pivot swingarms that flex,and always at the axle.

honda had the right idea apart from they run a regular 12mm thru axle,should of gone for a 20mm thru axle rear.
