The adapter can be thanks to the sufficiently long tensioning belt, which is also inside even rubberized, non-slip and easy fix. My attachment location is the seat tube. Locking takes place so that there are two small noses / cams are in the closing piece, which are guided against the abutment, then by closing a kind of eccentric running and the shutter is closed. Here is the adapter at no description from which the can be seen, as well, is not as described, that pressure on the orange button opens up the possibility to adjust the adapter into the slope. What has prevented an assessment with 5 points is the fact that you have the shutter spendiert no assurance that can prevent an unintentional opening, eg when driving over bumpy ground. When the eccentric effect should be even weaker, which for example may be due to media expansion or fatigue quite times, then the closure could possibly be opened easily, if he did not re-adjusted on the adjustment of the belt. It may be that I'm here too cautious and think, but since I do not intend to ever solve adapter and reattach it I have even created by this assurance that I once pulled around a fabric tape. A small plastic latch with a spring factory, which could take them to secure the closure piece and the adapter would be perfect.
