I have just bought a Trek 7.2 FX 2014 edition used but in very good condition (virtually new). It still has the grease on the seat post. It doesn't feel right though compared to my Tricross. I spent the last 30 minutes figuring out where the difference is. My leg doesn't feel like its extending enough when cycling. If I put the saddle any higher, I cannot touch the floor when on the saddle. Measuring from the floor to the crankset, the Tricross is 11 inches and the Trek is 11.5 inches and I think this is the main issue.
Hmmm.What to do next
Well when I say touch the floor, I only mean fully stretched tiptoes. When I stop at lights I can remain seated and get my toes to touch the road by leaning to one side.You shouldn't be able to put your feet on the ground when on the saddle, if you can the saddle is the wrong height for you.
Not when clipped inEven so your leg should be a full stretch when the crank is at six o'clock.
