Replacement set for our QMR mounting system 2.0. Includes two hooks and a handle. QMR is a high quality, technically sophisticated mounting system for quickly attaching and detaching your bike bags. The set is also compatible with the old QMR system – because long-lasting products are good for the planet. For those who are planning longer hikes, a spare set is recommended in case you walk on trails with a lot of rocks or bushes. If the side pannier, attached at the Monowalker rack gets stuck on a tree or rock, it can tear off. It has no weight and can help in an emergency case.
