Will it fit your bike?
We checked this bag against 347 current bike sizes with published geometry. It fits 332 of them — 96%.
Frames it doesn't clear include Salsa Cutthroat 52cm, Salsa Timberjack X-Small, Salsa Fargo Ti X-Small and others — almost always the smallest sizes, where the front triangle runs out before the bag does.
Judged on Revelate Designs's stated minimum seat tube and top tube, plus front-triangle area so that sloping frames aren't wrongly excluded. It's an estimate from published numbers, not a guarantee — measure before you commit.

Manufacturer specifications, compared against every other frame bags in our database. We do not test gear in the field — we measure, verify, and compare.
The Ranger is Revelate's full-frame bag built with their waterproof Spindrift fabric. Custom-fitted to your frame geometry, it maximizes cargo space in the main triangle. The internal divider helps organize gear, and the bolt-on mounting system eliminates strap creep.
The Revelate Designs Ranger has been a staple of the bikepacking scene since the early days of the modern bikepacking movement, and for good reason. Built in Revelate's Anchorage, Alaska workshop, the Ranger represents years of refinement from a company that essentially helped invent the modern bikepacking bag category.
The standout feature is the Spindrift waterproof fabric. Unlike many competitors that rely on water-resistant coatings that degrade over time, Spindrift is a laminated fabric with welded seams that stays waterproof season after season. Revelate rates it as fully waterproof rather than water-resistant, which is the claim that matters for a frame bag sitting in road spray; how it holds up over several seasons is not something we have put it through. That matters when your spare clothing and electronics are inside.
The bolt-on mounting system deserves special mention. Most frame bags use velcro straps that slowly creep and loosen over rough terrain. The Ranger's bolt-on system uses small hardware that threads into existing bottle cage bosses and dedicated mounts. Once installed, this bag does not move. Period. On washboard gravel roads that would have strap-mounted bags shifting constantly, the Ranger stays planted.
Inside, the internal divider is a thoughtful touch. The sensible split is heavier items — tools, spare tubes, a battery pack — on one side, with food and quick-access kit on the other. The divider is removable if you need the full volume for larger items.
The custom fit option is worth the wait. You submit your frame dimensions and Revelate builds a bag that fills your triangle precisely. Off-the-rack frame bags always leave gaps — wasted space where gear shifts around. A custom Ranger maximizes every cubic centimeter.
Where the Ranger falls short is value for money. At $155, it's significantly more expensive than entry-level alternatives like the Topeak Midloader. And the custom fit option adds lead time — expect 4-6 weeks. For riders on a budget or those who need a bag tomorrow, that's a real consideration. But for serious bikepackers who want a buy-once-cry-once frame bag, the Ranger has earned its reputation.
Who Is the Revelate Designs Ranger Frame Bag Best For?
Riders who want maximum frame bag capacity with waterproof protection. If that describes your riding style, the Ranger Frame Bag should be at the top of your shortlist. It sits in the Frame Bags category alongside 16 other products we track.

The price-to-weight ratio comes in at $46 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.

The Bottom Line
We haven't scored the Revelate Designs Ranger Frame Bag, and neither has anyone else we can cite. It's here for its verified specifications and dimensions, which is what the fit tools run on — a score is an editorial judgement, and we don't hand one out until someone has a basis for it. What this page can tell you is measured: 340g, $155, and how both sit against every other frame bags product we track.

How it compares
Against the 17 frame bags we hold published specs for.
At 340g the Ranger Frame Bag is lighter than 1 of 16 alternatives we track, which makes it among the heaviest we track. The category median is 198g.
At $155 it undercuts 7 of 16 of them, against a median of $151. That works out at $46 per 100g — below the $69 median for frame bags.
Weight and price come from published specifications. Cost per 100g is a blunt measure — it rewards light gear and says nothing about durability or whether the thing works — so treat it as one input, not a verdict.
