I just picked up a Topeak TourGuide handlebar bag. The kit comes with two adapters for diff. diameter bars. Unfortunately, the diameter of the stock bars on the LHT fall between the adapter sizes. I'm thinking I can pad out the bar with a couple wraps of an old inner tube, but am concerned that it will still slip. Anyone here have similar experience?
Can't tell how that is made on the bottom, from the picture at Topeak, but the Nashbar bag that I have came with two different sized pieces of rubber coated metal that you attach (the one that fits best) to the screws and runs under the part of the stem that goes toward the front. If you can possibly do something similar to that it will not be able to slip down do to the weight of the bag. Hope this helps.

For now, I was able to fit the 25.4 adapter on the left side (which has a longer screw than the right side bracket), and the 28.6 adapter on the right with a section of inner tube wrapped underneath. I was able to get it very tight, but haven't had a chance to road test it yet. It looks like it should be ok.

Weight of the handlebar bag should not be maintained by the handlebar clamps. Instead, the metal wire that wraps around the stem is what carries the weight, and once that is tight, your handlebar bag won't slip.

I know the wire keeps the bag from slipping. Are you suggesting that the clamps do not need to grip the bar at all? I can get the fixer 8 to fit with the oversize bar adapters, but could not get it to "clamp" to the bar at all.
I've misplaced my calipers otherwise I could confirm that the bar diam. is in between the sizes that the adapters were designed to fit.

Sorry, not suggesting the clamps are not needed, only that the weight of the bag is supported by the wire. Clamps will be needed to prevent mounting bracket from sliding left-right and from bouncing as you ride. I think the tube wrap you used would be sufficient to tighten clamps enough to prevent sliding and bouncing.
