What bottle cages do folks use to securely carry on-course bottles at US races?
I’m new to triathlon and recently did IM 70.3 Santa Cruz. I took a bottle of water at the first bike aid station, tried to put in my BTA cage (Xlab Vulcan) and saw it was too small and would probably slide out if I didn’t hug it. I put it in my BTS cage (Xlab Xenon) and 5 secs later in launched (fortunately within the aid station zone).
I’m dong IM Arizona next month and would really like to hold onto bottles. I saw several athletes at Kona carrying on course bottles, so at least I know it’s possible.
