Our inspiring overview is coming soon. For now, here is what Revelate Designs has to say:

We set out to create the most stable, low profile mounted, feature loaded, waterproof seat bag available. The Spinelock seat bag checks all the boxes.

The Spinelock integrates user tested and approved features like a one-way air purge valve, rear light slots, loop and bungee deck, and an external plastic bottom with a new patented attachment system. Stability was the driving element in the design process. If you want something you can pack and forget, the Spinelock is your seat bag.

How it works: 

The Spinelock stability system consists of three components: the saddle clamp, seat bag mounted “Spine” baseplate, and pin.

A low profile, high strength, forged aluminum clamp works in combination with precision IGUS bushings to form the pin interface. Twin forged upper arms, fastened by Torx-25 bolts, rotate into position above the saddle rails for easy mounting.

Resembling a spine ramp familiar to skateboarders, the “Spine” baseplate is made of an impact resistant UV-stabilized nylon and is integrated to the seat bag surface. The plate features two mounting positions to accommodate seatpost setback and saddle adjustments. To connect the bag, you simply line up your selected mounting position to the seat mounted clamp and slide the pin through the aligned holes. Attaching the side compression straps to the wings of the clamp fixes the pin in place and you’re ready to ride!


There are two size options, neither of which sacrifice features for capacity. The Spinelock 16L is our largest seat bag and is perfect for longer trips, cold weather adventures, or if you just like to pack extra. If you have minimal tire clearance or are going on warm weather adventures we recommend checking out the Spinelock 10L.

The Spinelock 16L requires 9.5″/24 cm tire clearance and 6.5″/16.4 cm exposed seat post.

Important information on use and fit: 

  • The Spinelock bag is not compatible with carbon fiber saddle rails.

  • A Torx-25 wrench is needed for installation. you likely already have one on your multi-tool!

Good company. Defective item.

The item was, unfortunately, defective and was sent back to Relevate Designs for a replacement. Not interested in casting blame and being negative. Such things happen from time-to-time.


Revelate 16L on a dropper post

Bag works great to hold my 20 degree bag and UQ. I’m using it on a Kona Hei Hei DL with rear suspension locked out. If you don’t lock out the rear it will rub during travel. I also can’t use my dropper, but that’s a small price to pay for the size of the bag. Item was shipped super fast and folks at Campfire are awesome.

Getting my order placed and received was smooth as silk. Efficient, fast turnaround and the Revelate bag is outstanding. Thanks Campfire!

Revelate Designs 16L Spinelock Seat Bag

100% would buy again. Rode fully loaded for 80 miles on gravel. Zero sway, I actually forgot it was back there. The vent tab was very helpful when compressing the bag to get it as small prior to securing to the bike.

Great bag!

Super stable, no rocking back and forth. The Spinelock system is rock solid and super easy to use.
