I have a klick fix, but it keeps bouncing up when not heavily loaded when I go over speed bumps. I have my handlebar setup with a loop of wire going over bars and under the stem, like this

I was wondering how I could stop it from bouncing up. I had an idea of how to do it with a pedal strap, but it was too short. I was trying to work out how to do something like this

If you can't get the Klickfix to stay put completely the Ortlieb bracket is an option worth trying. The design accounts for this, the cable fitted, tensioned and locked off prevents the bracket from jarring both up and down. I've found it to be better at staying put when riding over rough ground.

Have you got the screws tight enough?

It looks to me as if the KLICKfix doesn't winch the cable tight in the same way as the Ortlieb: is that right?

That's correct. The important part is to do it in the right order, tighten the cable with the bracket slightly upwards, push it down till the cable are tight, then do up the screws. If you tighten the cable with the bracket already level, it'll never be tight enough. It's there to stop the weight in the bag from dragging he bracket down, the bracket should be pretty firm without it. I had a basket on the front of my delivery bike attached with this bracket, frequently 7 - 10kg, and it never moved, if a bag is bouncing about, it isn't fitted properly.

Thankyou.

I've got pretty old versions of both so I'm presuming that they still work in the same way. You are right, winching the klickfix cable with a threaded tensioner (as is the Ortlieb design) would force the bracket to rotate upward as it overcame the friction of the clamps.

With Klickfix, the cable only supports the clamps in one direction, stopping the bracket from dropping once the cable is tensioned correctly.

This is easy to do; set the angle of the bracket a bit higher than you want, pull the cable as tight as you can and secure it, then push down on the bracket to lower it which will fully tension the cable. Finally fully tighten the bracket clamp screws in that position.

The Klickfix bracket relies entirely on the friction of the plastic clamps on the bar to prevent upward movement. For most scenarios this may be adequate but for my usage it wasn't, and the bracket would gradually work its way upward when riding over rough ground, despite the clamp screws being as tight as possible without stripping the threads.

The Ortlieb works in a completely different way. There are no clamps so the cable needs to be very tightly anchored in both directions around the stem head, but once installed correctly the bracket is locked to the angle at which you set it and it can't move either up or down.

The necessary cable tension is achieved by a threaded winch and the bracket is fully secured by tightening the final grub screw, which locks the position of the bracket on the cable.

Thankyou

I have both fixings and prefer the klick fix for its simplicity and the ability to remount it more than twice. My Ortileb is on its third mounting but it was extremely difficult and I won’t even attempt a fourth. It will be new cable next time it moves bikes.
I’ve never had any movement with the Kliick fix but I usually, out of habit, put a bit of old inner tube on the bars where it clamps. That probably helps to nip it up and stop any movement.

Just an OT note for anyone interested, it's fairly well known but just in case anyone doesn't - The Ortlieb bags fit the R&K bracket, but it doesn't work the other way round.
The exception is if one or the other (I can't remember which) is really old and then one part needs a slight modification.

Another advantage of the R&K Klick Fix bracket is that the simple support cable can be replaced with a length of redundant brake cable, if it eventually becomes too frayed to reuse. I generally sheath the brake cable in a length of pvc insulation to protect the stem and bars.

I use a couple of wraps of electricians tape around the bars. I haven't bothered with the cable. The same on my single and tandem and the bag does not move!

As above. Little bit of tape first to give the bracket something to dig into then set it slightly tilted up at the front. Once the cable is very tightly tightened lean on it and do the clamps up. I have seriously over loaded mine and it never shifts.
When the cables die use old brake cables and if you ever strip the thread on the plastic clamp bits use wood screws with a bigger diameter.
