Finally, the 7.5 does also have the E2 tapered head tube and steerer, which due to its shape, helps to keep the system stiffer under pressure, more evenly distributing cornering forces for stability, and longer-lasting bearings.

As for the new FX, the entire line will now be compatible with Bontrager DuoTrap S speed/cadence sensors, which mount into the bike's non-drive-side chainstay. DuoTrap S will be both ANT+ and Bluetooth, so it will work with various cycling computers or your smartphone. Some of them will also come with Blendr stems, which include integrated mounts for a light, computer, or iPhone case. The whole thing sort of works together for a seamless, clean, and easy-to-use bike computer or fitness tracking system. Beyond that, the frames may have received a slight redesign (not sure on that one), and there are some new color options coming out.
