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.

*The product classification of the ergotec Safety Level complies with the DIN EN ISO 4210 standard for bikes and DIN EN 15194 for e-bikes. The ergotec Safety Level is always valid for the entire steering system. If stem and bars have a different safety level, the lower value will apply to the entire system.
Due to safety concerns, the manufacturer does NOT approve the use of the stem with carbon handlebars and/or carbon steerer tubes.
