Just curious if there will be pumps with air gauges and chain lube at some controls?
I really don't understand this question. I can't think of a scenario where I'd be thinking "thank goodness there might be a decent pump at the next control, 80km away, that might be lost, broken, or missing". Wouldn't a better option be to carry a good pump? I carry a Topeak Road Morph (with gauge), with which I can achieve full pressures without too much difficulty. Those mini-pumps strike me as a waste of weight, however light they may be, if they are not up to the task.
I also don't understand CO2 cylinders for Audax although I'm sure they have their use in short lap racing. How many to take for 1400km? I'm sure I'd end up taking a pump anyway just in case I ran out of cylinders, in the same way that I take patches as well as spare inner tubes.
