What do you guys think is the optimal travel for a 29er hardtail with a sus fork up front? I really like the rigid ride in the technical, rocky singletrack around WV, but can't hang on the creekbed type fireroads we have around here. granted, my right arm has no muscle left due to being immobilized for months, but i was thinking that a 2.5 inch travel fork would be about all i needed with big wheels to maintain better control untill i get my strenth back. anyone with experience with care to enlighten me? thanks.
