Pimp My Bike:

Step 3: Carry More Stuff

If it's a remote location (Kananaskis back country) I'll throw on a rear pannier for stove, more water, mini shelter, maps, space blanket, etc. I keep a can of bear spay on my battle belt, although I hope I pedal faster than angry bear. I even drag a trekking pole or two along, if a hike is part of the plan. I made these rear bags out of old ruck sack parts.

Always have a map. I've found that even if I don't need it, I meet people on the trail who do.
Before I go on, I feel I'd be remiss if I didn't mention safety.
