Hows it going,
I just got a Trek 7.5 FX 2 weeks ago. This is my first experience with clipless pedals and i went with the Shimano M324 SPD pedals. Ive put in over 300 mile so far and am very happy i went with these. They are very easy to get in and out of and i picked it up very quickly. They also have a 'normal' side so i can wear regular shoes when i need to or not clip in when needed. The SPD shoes have the cleat recessed into the shoe so i when im off the bike their pretty comfortable. Ive done 15 mile rides and as much as 50 so far. As someone who just went from normal pedals to clipless i am very happy i did and am not sure how i went without them before.

One more thing to consider with the 2011 7.5 FX is the handlebars, i have a post in my blog that explains a bit more. http://bartsbiking.com/ But i am extremely happy with this bike.
