well, i suppose it was just very hot and humid and in favour of the athletes they can allow it...why not?

I think in favor of the athletes they should allow it all the time.

The reasons in favor of allowing it: effective cooling, hydration storage, trash storage.

The reasons for disallowing it: Looks goofy and provides marginal aero helmet-like gains.

I think you guys are overthinking it. All you need really is a more extreme version of what Sam Long already has between the arms.

Just move BTA hydration up and back to the same position it would have been had it been down his shirt. If you need to, get a longer/bigger bottle or an adapter that allows you to mount 2x bottles back to back. If you need the extra fluid, fill it up, but there's no reason (especially if you're worried about it structurally) it needs to be filled.

This comes with the caveat that this is obviously much less safe than just stuffing a bottle down your jersey (which is why I think the rule should be changed back), but there's nothing stopping us from just creatively using hydration bottles like Joe Skipper, only between/behind the arms, so long as it vaguely looks like a BTA setup that's already otherwise common.

Have you aero tested showing they are the same?

It is addressed in this video or the previous one

Did he use that bottle during the race?

Tririg is now selling a part to raise up the bottle.


You can see it here in their video.





I may have missed it, but I haven't seen a "why" for the banning of the bottle down the kit. This, along with the banning of taping aerobar extensions together can easily be viewed as a cash grab. I understand the safety part of things- has Ironman said we aren't allowing this because it is more dangerous?

Unfortunately that only works with their bikes I think? The spacing of the bottom holes don't line up with a normal bottle cage position. I can't remember the name of it, I believe it was made by profile design, but I ordered an extender piece I was able to add to mine and bring it up 80mm from the bottom of the bars. I wish it was bout 5-10mm taller. This is the perfect area where 3d printing something is ideal.

The Tri Rig BTA extension works on my 2nd Gen Speed Concept

Nice! Looks like you made it work by mounting it upside down compared to how they show it? Without that additional angle bracket I guess you couldn't attach a bottle cage to it when it's reverse. Looks great.
