There's no doubt the RIZA is Chromags finest stem to date. CNC machined in Whistler, Canada from premium 6061 billet aluminum, it features the new faded edge on the clamp face to help avoid hot spots and stress risers when your bar flexes under load.

Also it looks really flippin' nice. 

The RIZA comes in 31.8 and 35mm clamps and 32, 38 and 45mm lengths.
