Chromag Stem Direct Mount Riza 35Mm Black"Everything you love about the RIZA (who says you can't love a stem?) but in direct mount! We've used our knowledge of making stems for almost 20 years to create a new, highest level bar grabber. There's no doubt the RIZA is our finest stem to date. CNC machined from premium 6061 billet aluminum, it features our new faded edge on the clamp face to help avoid hot spots and stress risers when your bar flexes under load."
