WOW. I wrote to Kris Holm just before I posted this question thinking that he might be too busy to answer but Kris wrote me back already!
That is really cool of Kris.
Here is the message he sent me.
"Todd,
Thanks a lot for the note and the interest.
The differences between the '09 and '08 are:
New Fusion Freeride saddle with upgraded saddle frame and rear bumper This is the most obvious difference. If the attachment bolts for the bumpers and seatpost are hex bolts (instead of dome nuts) it is the 2009.
Spokes are 14g (were 13g)
New Moment hub (was blue, now is black, with upgraded flange design). The first '09 hubs were all black but there was a mid-season changed to polished flanges; both are '09 hubs.
Hope that helps.
Cheers,
Kris"
Makes me happy to support him by buying his products
