I finally got sick of thinking about what fork to get for my Sette Shadow so I snagged a 55 r from Jenson for 209 out the door. I did this over buying used to a) get a brand new fork and b)make sure I get a warrenty c) it was a damn good price.
I talked to a guy that wrote a review of the frame on MTBR who is running an 140mm AM 2 fork and he said he wouldn't consider running a fork with less travel so I figured what the hell.
The AC on a dj1 (that I was also considering) is 490mm on the 55r its 521mm, considerable but not to huge. I also figured out that it is pretty easy to lower the fork if need be. I think this will work out well and not throw off the geo to much.
I need to say thanks to chelboed for the idea of the HTFR build and the fork. I hope we can ride soon. Bring the hick too.
