I am wondering what the largest BTA bottle people are using…that has a straw. Kind of like the xlab torpedo or Profile design Aero HC system. I would like a straw and refill option.
I was using a Profile Design FC-35. It holds 35oz, but since it’s mounted to the bars, if you tilt the bars you lose some capacity. IMO it also looks bad when you have the bars tilted.
I’ve since moved to the Aeria hydration system, which holds 30oz. It mounts to a bracket on the stem so it’s not affected by bar angle. Downside with this one (aside from 5oz less capacity) is that the straw overlaps the refill port, so it’s more awkward to refill.
I’m thinking of building up a double BTA setup a la Ben Deal, then aero testing all three with mywindsock this offseason.
