Ironman - Arizona

Rear: Sub-9 Front: 808 The long uphill drag of the Arizona course is so gradual that an ultra-aero setup like a Sub-9/808 is worth a few extra grams, especially if you’re fighting a headwind on the return leg of the out-and-back.

Rear: 1080 Front: 404 Going one step shallower for both wheels, from a disc to a 1080 in the rear and from an 808 to a 404 in the front, lets you press your advantage on the climb with a minimal aero penalty on the way back.

Rear: 1080 Front: 404 The same 1080/404 setup also gives you flexibility when the wind kicks up and bike control becomes an issue. A 1080 rear will exert no more side force than a tri-spoke, while a 404 front optimizes handling and aerodynamics.

Rear: 808 Front: 303 This wheelset will help you maintain your concentration and confidence while you dodge the tumbleweed. Smaller riders especially will appreciate the low-profile 303 front wheel combined with an 808 rear.
