I'm looking at the parcours of the ride outside Nice, I've ridden around this region of France which is rather lumpy including one major climb, OK 2,300m of climbing over 185km is not a huge amount of climbing but some of those decent's are quick and technical, there seems to be little flat. In this case why the need for tri-bars?
I see an issue of the tri-bars getting in the way of climbing and down hill at speed especially.
I have an advantage of others in that my best ability in Ironman will be the bike, but I question the purpose of tri-bars or a tri bike on this particular course, I can't see this helping at all apart perhaps from the final 25-30km.
If anyone has done the bike course, please let me know if you agree with me or suggest why I should chose tri-bars, maybe I'm making the wrong assumption here.
I'd also question the pros using tri-bars, when you going downhill on technical decent's @60-80kmph you won't be using tri-bars! or even that matter deep section wheels for example 404 Zipps would be ok but 808's would be no benefit at all and will be dangerous especially if there is any rain.
