HED took the Grand Tour-winning H3 tubulars and made them wider to reflect modern tire preferences. Gone are the day when riders were running 18mm tires—they want the ride quality, speed and comfort of wider tires. These full-carbon GT3 tubulars slice through the air with amazing efficiency. Three airfoil-shaped "spokes" that transition gently into a 46.5mm-deep rim are the key. The rim cuts through the air when the wind is mostly head-on, and when the wind is from an angle, the tri-spoke design goes to work to keep the drag low. All this means the GT3s are faster in any conditions than a traditional spoked wheelset. That's the reason why you've seen these wheels ridden by the fastest time-trial and triathlon riders in the world.
These wheels require tubular (sew-up) tires.
