Been threatening to do this for some time but finally pulled the string...I ordered a Yeti ARC mountain bike for the sole purpose of bike camping with my hammock. I've been picking up parts here and there, watching sales and buying used where I could, should have all the orders in by this weekend.
I also ordered a Revelate handlebar bag and a Freeload Tour rack for the rear.
Bike should be pretty light even with the bags, it's a mix of SRAM X.0 and X.9 components along with a Shimano XTR crank, Thompson stem and seatpost, Easton carbon fiber bar and Mavic Crosstrail wheels. I could have bought a camping trailer for less...
Interested if anyone else is doing mountain bike camping, would love to share info on your setup, what you took, etc. I did a dry run last weekend by packing in on the Ozark Trail, setting up camp, running back to the car, then riding my bike. Fun but a lot of hassle. With the new bike I should be able to get 100 miles of trail covered easily. Or just find a great spot to use as a base camp and ride the fun sections.
