save your money and buy the EX8, it's a massive upgrade from the EX7. The RE:Aktiv shock being one of the most important differences. When I bought my 2016 EX8 I also rode the EX7. Wow what a difference in the ride, you couldn't even compare the 2 bikes I felt. I'm so happy I bought the 8.
the EX8 has the Fox34 shock, the RE:aktiv rear shock and a dropper post. You don't get any of these with the 7
