Product info

The new high-end Quantum Lite is a perfect stem for Enduro, Trail riding and Dirt Jumping. Designed to work with 31.8 or 25.4 bars, it looks smart and is superlight yet very stiff. You will not feel any flex, even with the widest bars. The stem is cold forged from quality AL6061-T6 in our own moulds before going into the CNC department for full surface machining.


The short reach makes it the perfect choice for bikes with modern geometry. It has a knee friendly steerer tube clamp design and a 'no gap' front plate system that gives a unique, smooth look. It's one of the lightest stems on the market, however strong enough to survive even heavy duty riding.
