The Quark Pro stem is available in 25.4 and 31.8 sizes. We optimised the faceplate and body, and removed every unnecessary cubic millimeter of alloy from this stem. But no worries about the strength - the Quarks are cold forged in our own moulds before going into the CNC department. This whole process improves the characteristics of the material. The short reach and zero degree rise makes it the perfect stem for new school riding.

The Quark has been on the podium of the FMB World tour more times than any other stem.
