Ritchey WCS Carbon Matrix C220 84D Stem – 110mm, 31.8 Clamp, -6, 1 1/8″, Carbon,
With the WCS Carbon Matrix C220 84D Stem, you really can have it all. The C220 handlebar clamp design creates a more secure interface by wrapping a full 220 degrees over the handlebar. Bolt forces are aligned with the clamp so that the stem body embraces the handlebar, which is less prone to damaging lightweight bars.
