Felt has just gone all-in on the tri market, releasing a brand new model called the IA. This 'Integrated Aero' bike has massive frame members, internal storage, integrated brakes and bars, and a radical new seatpost design that promises greater comfort on the bike. The IA is the first bike from Felt that truly embraces the concept of an integrated design. The aerobars, stem, brakes, and on-frame storage units are now completely proprietary and unique to this bike (along with, as usual, the fork, seatpost, and headset). The aero chords created by the frame are easily the longest on the market, and promise to be extra slippery in the wind. This gallery (and the detailed image captions) contain all the ins and outs of this brand new mean machine. Enjoy!
Now this one is intriguing. Felt has completely redesigned the aero seatpost. Instead of using clamping forces to 'crush' the seatpost into position, Felt has created an inside-out clamping mechanism that pinches the sides of the seatpost against the sidewall of the frame's seat tube. The result is that first, the seatpost can be made much lighter, since it doesn't have to resist clamping forces. But second and more importantly, the seatpost can now be built with a significant amount of vertical compliance, making the ride that much more comfortable. I'm very interested to see how this feels out on the road.
