Abstract: For the connection to a bicycle handlebar, a bicycle handlebar stem comprises a receiving element at a front end or is formed integrally with the bicycle handlebar. Further, a receiving space is provided for receiving the steer tube. Using a fixing element, it is possible in particular to clampingly fix the steer tube to the bicycle handlebar stem, in particular in the receiving space. The receiving space is configured such that the steer tube can be connected to the bicycle handlebar stem at different positions without the steer tube protruding beyond an upper side with respect to the bicycle handlebar stem.
