PZ Racing Components
 

I know there is already a thread on this, but thought I would ask again hoping for more/better responses. Does anyone have experience with these components, especially the 3.1 Carbon Stem? How do they rate in stiffness and weight to others such as Ritchey WCS or Deda and maybe others. Any pro teams out there sponsored by them? The 3.1 Stem looks hot, weight I believe is 150g

PZ=high quality, reliable, inexpensive components
they're overall good
but most carbon stems are heavy. choose aluminum if you want a light one
