OK, new seat installed. The specs read 10mm lower (which is about 1/2 an inch.) But as you'll see in the pics, the profile of the seat is different as well, and I gained over an inch, possibly 1.5 inches. It still seems as comfortable, but the major road test is set up for Monday (I and both of my riding buddies will be out of town, all at separate locations for the weekend).
Here are the two seats, the original on the left, the lowered assy on the right.
I did it immediately after work, so originally I was in my sandles.
Then I changed into the boots I wear to ride in:
Both feet down:
And one foot on the pegs, one on the ground. Bike still verticle:
I'll let you all know how it feels after I get a few hours in the saddle on Monday. But I think this will work for me.
