I just barely have room to attach a front pannier when the low rider is installed...

Tried this on my straight blade carbon fork. No go. I can put the zip tie above the existing braze on for my brake cable holder and the bottle stays up where it should without falling but it just spins around too much and eventually rotates around closer to the wheel. I'm sure some duct tape would keep it there so I'll consider this idea as a distant third option
Unrelated to this but related to the original thread. All my bikes use the same cheap composite ones, Zefal "Spring", about $5. Over 10 years with no problems and I haven't broke one yet. They hold a wide range of bottles and they even stay secure on singletrack, over logs, washboard etc.. Only problem is small 16oz water bottles will sometimes fall out but I rarely use ones that small. Unless I wipe out, nothing else has fallen out. They do tend to scratch up the bottles but that doesn't bother me.
