Revelate Designs Joey Downtube Bag 1L — Specs & Analysis
Manufacturer specifications, compared against every other frame bags in our database. We do not test gear in the field — we measure, verify, and compare.
A fully welded 1-liter roll-top that straps to the underside of your downtube — the least-used real estate on most bikepacking bikes. Silicone straps and a moulded foam pad keep it from wandering on rough ground.
Look at a loaded bikepacking bike from the side. Frame bag, seat pack, handlebar roll, top tube bag, fork cages. Now look underneath the downtube. On most bikes that space is empty, and it's the single best place on the bicycle to put weight: low, centered, and out of the wind.
The Joey is Revelate's answer. 17.8 x 10.2 x 10.2cm for 1 liter, fully welded with a roll-top closure, mounted with silicone straps over a compression-moulded foam pad.
The foam pad is the detail that makes it work. Strap-mounted bags on round tubes rotate — that's just physics, and on washboard it happens fast. A moulded pad plus silicone straps is meant to give the bag a flat, high-friction interface with a round tube instead of a strap biting into a curve.
One liter is a tube, a pump head, a multitool and a couple of CO2s. Or it's your stove and fuel canister, kept away from your food and your sleeping bag. Or it's the greasy stuff. Riders use it for whatever they'd rather not have inside the frame bag, and it takes road spray head-on, which is exactly why the welded waterproof construction matters here more than almost anywhere else on the bike.
108g and $75. Note that the position taxonomy on this site doesn't have a separate downtube category, so it lives under frame bags — but it mounts under the downtube, not in the triangle.
Who Is the Revelate Designs Joey Downtube Bag 1L Best For?
Riders who want tools, fuel or the greasy kit out of the frame bag and down low. If that describes your riding style, the Joey Downtube Bag 1L should be at the top of your shortlist. It sits in the Frame Bags category alongside 16 other products we track.
How It Compares
At 108g and $75, the Joey Downtube Bag 1L is 8g heavier than the lightest option in this category (the Apidura Backcountry Frame Pack 1L at 100g). The most budget-friendly option is the Moosetreks Full Frame Bag at $60.
The price-to-weight ratio comes in at $69 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.
What We Like
- +Uses the downtube — the most underused space on the bike
- +Fully welded waterproof, which matters under road spray
- +Silicone straps and moulded foam pad stop rotation
- +Weight sits low and centered
Watch Out For
- −1L is small — this is a supplement, not a system
- −Needs downtube clearance; suspension and some frame shapes rule it out
- −$75 for 1L of storage is not cheap
The Bottom Line
We haven't scored the Revelate Designs Joey Downtube Bag 1L, 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: 108g, $75, and how both sit against every other frame bags product we track.

How the Joey Downtube Bag 1L compares
Against the bags people cross-shop it with, measured rather than reviewed — including how many real frames each one fits.
How it compares
Against the 17 frame bags we hold published specs for.
At 108g the Joey Downtube Bag 1L is lighter than 15 of 16 alternatives we track, which makes it among the lightest we track. The category median is 198g.
At $75 it undercuts 14 of 16 of them, against a median of $151. That works out at $69 per 100g — above 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.
