NS Bikes Quantum Small Stem

The high-end Quantum is available in 25. The small bar bore version is 37mm following requests from dirt jump riders.

The oversized version is 45mm length making it perfect length for Freeride/Enduro use. The Quantum is cold forged from quality AL6061 T6 in our own moulds before going into the CNC department. The short reach comparing to most stems on the market and zero degree rise makes it the perfect stem for new school riding. It has a knee friendly steer tube clamping design and a 'No gap' clamping system gives a unique smooth look.
