PRO Koryak Di2 Alloy Stem

A sturdy stem in looks and performance, the Pro Koryak Di2 Stem is a great choice for everyday mountain bike riding.  The square profile boosts strength and the four-bolt front clamp allows for increased lateral rigidity when using wide bars.  PRO also chooses to use 7075 aluminium alloy in this stem to give the maximum possible strength while keeping weight low at 110 grams in the smallest size available.  This version comes ready for integrated internal routing for Di2 cables but can still be used in an alternative set up If needed.  If you want a stem that will boost your confidence on the trails with sharp cornering and a responsive stiff feel when out the saddle, the new Koryak is a great choice.
