Quality of the support very well; the Assembly also works quite passable; you have to thank the manufacturers that there is this support at all - but it could be improved in one respect: If the holder would be designed so that you could put the brake and derailleur cables in the middle that would be optimal - or if the holder extension of the original Klickfix retainer could be used. So the trains have no optimal place. Therefore, the review "not bad". The problem, however, lies in the core at bicycle manufacturers, z. B. Kettler, do not lay the cable guides so that the front handlebar bags can be attached with the Klickfix system problems. An alternative is the aluminum holder of Schirmeyer. Meanwhile Shopping and see but to nothing and the Klickfix system is not kompartibel (most manufacturers of handlebar bags / baskets using Klickfix), there remains only this solution.
