Fits round and oval pipes. The fastener has been completely redeveloped. The compact design - 109x94x78mm - allows very easy installation even on frames with limited space. The adjustable clamp allows adaptation to different frame diameters. An additional advantage is the arrangement of the screws on the handlebar side and not on the wheel side, which makes tightening the clamp freer and more solid. For safety, the clamp is equipped with a lock that can be opened with a key.
