The Tech sheet only pictures a frame so I guess frame only? Ill weigh my frame and arm when I get the use of some scales. My arm tells me they are light!!

I have weighed a stripped large carbon frame including the swing arm fully fitted but with no shock at 2550g
an NR-2 shock adds 212g + a 550lb/in steel coil spring @ 286g (Ti = 148g)

thank you, swingarm weighs as much as the part itself

It helps to estimate a possible weight with different equipment (dt swiss carbon shock 160 gr, 60 gr a disc, seat etc.)

Formular one and moto GP use 'carbon' discs, are they the same as those?  The only problem they seem to have is that they dont work untill they are hot and they loose there heat quickly. So down hill riding might be good but XC riding maybe not so?

F1 uses carbon-carbon discs. Carbon fiber is used as a base material, but it is soaked in resin and then *burned* until only carbon remains. This process is repeated until the object is solid carbon.

Normal carbon fiber is soaked in resin, but the resin is cured, not burned.

These brake discs are made with special resin that contains silicon carbide, which is very hard and abrasive. That means the discs won't wear-down as fast as normal carbon fiber. However, the weave pattern shown in the pictures is NOT optimized for braking loads. I still wouldn't use them.

Rear discs are not difficult to install on your 4500 if you want to go with disc brakes in the front and rear

There have been many threads on this site on buying and installing an adapter or making your own.
