Ironman - Hawaii
Rear: 1080 Front: 808 Normal conditions at Kona are still quite windy, so we’d recommend sticking with the 808 in front. You’ll experience less side force than with a tri-spoke, and you’ll have the world’s fastest non-disc, the 1080, for backup.

Rear: 808 Front: 404 It’s windy out there even on a “calm” day, so many riders stand to benefit from the conservative choice of a 404 front wheel that can still cut through the headwinds you’ll face on the return leg.

Rear: 808 Front: 404 As you traverse the desolate lava fields, the last thing you need to worry about is keeping a straight line. Combining an 808 rear with a 404 front will help you relax and efficient as the day heats up.

Rear: 404 Front: 303 High winds on this course are nothing to take lightly, so smaller riders should consider the 58mm profile of the 404 as a rear wheel with the 44mm 303 up front. You’ll still get plenty of speed at just a hair over 1200g.
