Rack installed.
Bag purchased.

Just need the decaleur. The VO version is cheap—like 1/4 the cost of others out there. The others have more bolt holes (3 to 5 vs. 2), which makes me wonder if the VO has enough support. They also have all manner of widgets to make the more adjustable, but many of these seem like overkill.

Will the VO do the job? I'll be taking the bag on and off quite a bit, as a commuter, so if I'm going to generate tears in the fabric, I'll spend more for something with more bolts.

Thanks!

I won't rave about it, but it's fine. Its only there to stabilize the top of the bag. The headset mounting is a good way to do it.

The angle is likely to be wrong. Bend as needed after installation so you don't bend the ring that goes around the steerer.

One issue is the length. You really want the back of the bag to be in front of the front of the handlebar, so if you have a long stem the VO decaleur will be too short. But this is going on a xSogn, if my memory is correct? I think that'll be close but okay.

Another issue with the VO is the bar that attaches to the bag is solid steel. They make everything else from lightweight steel tubing, so this part seems stupid heavy. Attaching it to the bag should be the last thing you do, since it involves punching holes in the bag . Measure repeatedly, drill once.

AFAIK your rack underneath is what supports the bag , the top " decaleur " stabilizes it, front -back,.right -left ....

i realized yesterday I have two different versions of this. One is older, I think, and it's a flat bar. Probably not as strong, but strong enough, and you could drill more holes in it. I haven't.

I had one break on me at the weld between the round part that goes over the steerer tube and the part that attaches to the bag mount. It failed while I was descending a dirt road - got a replacement and it has lasted about 10,000 miles with no real issues.
