Mr. Fusion vs. Spinelock: The Most Stable Seat Pack?
In this video we take a look at two of the most stable and advanced bikepacking seat packs on the market: the Porcelain Rocket Mr. Fusion and the Revelate Designs Spinelock. Find a detailed review of both, how to properly install each one, and a comparison between the two.
There have been a lot of advancements in bikepacking gear over the years. That statement is especially true for seat packs. Small bag makers and larger companies have been tinkering, innovating, and creating solutions in attempt to craft the perfect bag. Two of the best and most advanced options currently on the market are the Porcelain Rocket Mr. Fusion and the Revelate Designs Spinelock. Both of these seat packs are 100% waterproof and have unique attachment systems to make them easy to remove and install, and act as stabilizer to eliminate side to side sway. Our YouTube channel host Neil Beltchenko tested both seat packs to find out which was the most stable. Her’s his detailed review of both bags.
Porcelain Rocket Mr. Fusion
The Canada-made Porcelain Rocket Mr. Fusion has long been one of our favorite seat packs. Not only is it completely waterproof, but the mini-rack/holster system prevents sway and movement. It’s also easy to remove and extremely durable (read my 5,000-mile review from 2016). In 2018, Porcelain Rocket reworked the strap system and introduced Mini and XL versions. The latest version released in 2019, which Neil tested, has a curved rack that better carries the load and the ability to run either 12 or 15 liter “DarkWhite” dry bags.

Revelate Designs Spinelock
From the outside, the Revelate Spinelock System seat bag looks a lot like any other bikepacking-style saddle pack, but its patented mounting system is different from anything else on the market. The Spinelock system offers a clever quick-release mechanism for getting the bag on and off for packing/unpacking, it’s 100% waterproof, and as Neil demonstrated, it’s quite stable. The Spinelock bags feature a one-way air purge valve, rear light mounting slots, a shock cord deck on the top to stash extra gear, and a skid plate on the bottom for durability. And it comes in two sizes to fit a wide range of bikes and riders. Find the specs below and read our full review here.
