Do you own shallower wheels for the front?

Pink? Maybe. Maybe not. You decide.

I can easily get one but not at this point

I ran 90 front and back for the full last year and was fine.

Just run the 90.

What do you weigh and how's your bike handling? If you're ultra light or not very confident, I'd drop the front down to a ~60mm. Otherwise, a 90 should be fine

You can perfectly use the 90mm profile. I ran in 2017 with Zipp 808 without any problem and it was a rather windy day.

Thanks, I figured I’d be able to power through. I’m a bigger guy at 6ft 190 and have dealt with some decent winds on the bike before without much issue on shorter courses.

I'm 5'11" and 170 and as above went with the 90mm front and back for the full last year, with no problems.

One piece of advice is to stay alert on the east side of the island. I saw two crashes, a minute or two after the fact, on that stretch that would likely have been caused by riders losing concentration and getting blown across the road into another rider. So while you will need to manage yourself, you should also keep an eye out for less experienced riders and pass wide - particularly on the second loop.

I was there in November for the full Iron. With my 120-ish pound weight, I had no trouble with the wind riding Hed tri-spokes. Other people on the course, however, was another story, but that comes with racing in a fatigued state. Keep your head up (at least once in a while ;-) and you should be fine.

Enjoy that aquarium-like swim!

I did the 70.3 in 2017 and there was hardly any wind, at least compared to what is usual. As mentioned above, the wind you will encounter is mostly on the east side. For the 70.3, this is in the first half of the course so you dont have to fight it when you are really tired.

Thanks everyone, this will be my first out of the country travel for a Tri and just want to make sure I'm setup as best as possible.

It sounds like you have made up your mind but I was going to suggest the shallower wheel. I did the full on an H3 Deep and regret it. If going back I would run a 404/808.

It's really hard to tell. The wind and direction can change making a 90 a poor choice. Or it could be calm making it a great one. Gauging it based on a particular past year experience wouldn't seem to be a reliable to way to make a choice (just like gauging 2019 swim time on any other year isn't reliable). In 2016, a disc would have been fine

Keep an eye on wind guru cozumel. what you really want to see is wind from the south, as the eastern side is the only real exposed side.

I'l be there again this year (knock wood). with a 60/90 setup. IMO the difference between 60 and 90 front is negligible at my speed, and the 60 is just more versatile (i've had enough races with a squirelly HED 3 front). It's not a place you can get a different wheel easily should conditions warrant. My .02
