ROSE Bikes Piranha 650B Stem| Stems For Threadless Steerers

It is vicious and robust – yet, the ergotec Piranha 650B stem is the perfect complement to 650B generation frames. Even though the stem with a 4-bolt handlebar clamp with a diameter of 31,8 mm and a shaft clamp of 28,6 mm is quite short with a length of 50 or 70 cm, it allows for a perfect riding position in combination with the handlebar. The ergotec Piranha offers you the possibility to individually adjust your handlebar/stem combo.
