I'm training and planning my first bike packing race/event. I ride a 2013 Niner Jet9 RDO which I plan on using for these events. My concern is, I don't see too many people riding full suspension bikes and I'm wondering why. Also, I would like a rear shock that has a better lockout than the Fox that's on it now, any suggestions? I've always been a hard tail rider until I hurt my back last year.
