Cyclocross bike and touring.

BPL member Nick Smolinkse makes bike bags (Rogue Panda). He's got an interesting under seat bag: http://roguepanda.com/2014/08/25/seatbags/

I've got one of these seatpost racks:

It's strong, light and pretty cheap. Certainly cheap compared to the Revelate seatbags. I've done some gnarly downhill with 10 lbs strapped to it and it's still going strong. Highly recommended.

I just did a California Coast tour. From Leggett in Mendocino County to Santa Barbara over 8 days in January.

If your kit is light enough, you can get away easy on that ride.

I rode a cross bike (Gunnar Crosshairs) with a frame bag and two rear panniers. I honestly only needed a single pannier, but brought two to balance the weight on my bike.

With a light backpack and by strapping a pad and/or stuff sack to your handle bars, I am pretty sure you can get away without needing any rear rack or seat bag.

Try to set your bike up with the gear before you worry about the rear end and see if you can make it happen.

I definitely had a bulkier quilt than you would need this time of year, and many redundant layers when I did the ride in January.

I love bike touring because depending on the route, you can get away without carrying much food o ra cook kit, and water is generally abundant. There are good food stores every day or two on that ride. Lots of places to camp, BEAUTIFUL Coastline, and great riding. The stretch of the 1 from Big Sur to Ragged Point is GORGEOUS!

Hope you can make that trip happen, you'll enjoy it, I am sure.

A bikepacking style seat bag ssems like a good combo with a frame bag and a handlebar bedroll. I dont think much of the clamp on seatpost racks. If the clamp doesn't hold, you'll have a little disaster on your hands.

If you do need panniers, you can use a rack that mounts on the axle skewer and a seatpost clamp like the one below.

For UL panniers, check out the Arkrel Dry Lites:

Bon voyage!

Craig,

I have a seat post rack with a bag/pannier combo you can have. I am in between a couple trips killing an hour on my iPhone and checking in with the boss lady. I won't have cell phone access until Mon March 23rd. Call me then.
