Spinelock 16 Seat Bag
Where to Buy
Revelate Designs Spinelock 16 Seat Bag Review
Tested and reviewed for bikepacking use
The Spinelock's rigid internal frame keeps the bag from sagging or swaying — the biggest complaint with most seat bags. The 16L capacity handles a tent, pad, and extra clothing easily. The roll-top closure is fully waterproof.
Who Is the Revelate Designs Spinelock 16 Seat Bag Best For?
Riders who hate seat bag sway and want stable rear storage. If that describes your riding style, the Spinelock 16 Seat Bag should be at the top of your shortlist. It sits in the Seat Bags category alongside 9other products we've reviewed.
How It Compares
At 395g and $170, the Spinelock 16 Seat Bag is 59g heavier than the lightest option in this category (the Apidura Backcountry Saddle Pack at 336g). The most budget-friendly option is the Topeak BackLoader 10L at $70.
The price-to-weight ratio comes in at $43 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.
