Would you still have hit it if your hands were on the brake hoods? Those things are pretty fast and I doubt you could have missed it, but I could be wrong.
.............I've been using these for three years and have never had an issue with reaction time. Even when not on the aero bars I don't have my hands on the brake levers. Do you? Same reaction time as being on the hoods. But, overall, the risk of that happening is dwarfed by the comfort and ability to go a LOT longer than I used to. I just can't do a pushup for two hours!
The hog came up and
hit into me and since it was 1:25AM, I didn't see it until it was at my leg.
