Are the Giant NRS all considered single pivot?The swingarm pivots around 2 sets of fixed pivots,and it has 5 sets of bushings on each side.It works pretty well-of course you give up downward suspension movement(gradual dips-huge dips won't matter),but bumps are probably a bigger deal.I set it up to allow a tiny bit of bob;it is a lot less stiff that way.An aftermarket link to increase travel improved it in that respect also.Depending on how you pedal,you might regain most of the force-energy use to bob-you will lose the friction energy of course..
I would appreciate a web address to something that describes single pivot etc.Thanks.Charlie.
