I’m looking to purchase a oneup mini pump. I’m concerned that the pump holder may not fit properly when attached to the bottle holder mount due to the width of the down tube on my Rail 9.
Sorry should have said this before. It’s the large pump with a fid-lock water bottle and mount. But only the small bottle would fit. I run that and a 2L hip pack for about 2 hours. Any more and you need a bigger bag.
Works for me on my XL. I also have a bottle cage storage container I stuff a backup tube (I'm tubeless), irons, multitool, c02, a couple of zip ties. I carry water on my back.
