Features: The Koski Stronghold Deluxe is a forged hollow stem of 6061-T6 aluminum with a four-bolt polished silver front plate. The shaft is matte black. The Stronghold Deluxe stem is available in two finishes, called “shot peened black” and “polished silver,” two angles, namely 7 and 15 degrees,and five lengths: 60, 75, 95, 110 and 130mm.
All of the bolts take a 5mm hex key.
Likes: This is a handsome and lightweight stem available in lots of finishes, angles and lengths. It is plenty stiff, and it has a large clamping area with the bar (these two features are probably interrelated).
