spent a ton of time researching this choice, and it was a tough
decision, but Marzocchi
garnered the win overall. The RockShox SID was a close
second. While the SID is lighter than the Z2,
I was astounded by the Z2's
massive weight advantage over the stock RST part.
It'll be a long time (if ever) before
my MTB skills even get close to taxing the performance capability
bottled up in this gorgeous package. See the reviews on this killer
part at mtbREVIEW.

I didn't get exact weights on these parts (had to use a spring scale
at the LBS as my O'Haus gram scale doesn't currently have the
capacity), the stock RST 381EL is a "boat anchor" compared
to the Z2.
