I am working on plans to do a Dos build up, and am curious if the '09 will be tooo relaxed with a 100mm fork. I prefer a more relaxed set-up, but don't want any of that floppy feel. The fork will be a F29. I ride a lot of technical terrain with roots and rocks, but it is mostly flat and fast. Also, can the F29 travel be adjusted? You know, buy the 100 and drop it to 80 if needed. Any help is appreciated.
