Revelate Designs Joey Downtube Bag 2L — 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.
The bigger Joey doubles the volume to 2 liters for the same $75 and only 28g more. Same welded waterproof construction, same silicone-strap-and-foam-pad mount, more room.
Two Joeys, same price, one holds twice as much. Unless your downtube genuinely can't take the larger one, the 2L is the obvious pick — you're paying nothing extra for the volume and 28 grams for the fabric.
22.9 x 12.7 x 12.7cm. That's 5cm longer and 2.5cm deeper than the 1L, and the depth is the number to check. A 12.7cm-deep bag hanging under your downtube eats into ground clearance and, on some frames, into the space where the front wheel swings at full lock. Measure before you order, particularly on smaller frames where the downtube is shorter and the wheel is closer.
What you get is 2 liters of fully welded, roll-top waterproof storage in the lowest and most central position on the bicycle. Weight down there does less to your handling than weight anywhere else — it's below the bottom bracket, so it lowers your centre of mass rather than raising it.
The silicone straps and compression-moulded foam pad are the same as the 1L, and they are the part meant to resist the rotation that works bare straps loose on rough ground.
136g. Filed under frame bags here because there's no downtube category in the taxonomy, but it mounts underneath, not inside the triangle.
Who Is the Revelate Designs Joey Downtube Bag 2L Best For?
Riders with downtube room who want the maximum benefit from the bike's lowest storage spot. If that describes your riding style, the Joey Downtube Bag 2L 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 136g and $75, the Joey Downtube Bag 2L is 36g 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 $55 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
- +Twice the volume of the 1L Joey for the same $75
- +Fully welded waterproof — built for road spray
- +Lowest, most central weight position on the bike
- +Only 136g
Watch Out For
- −12.7cm deep — check ground and front-wheel clearance on small frames
- −Not compatible with every downtube shape
- −Still a supplement to a main bag system, not a replacement
The Bottom Line
We haven't scored the Revelate Designs Joey Downtube Bag 2L, 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: 136g, $75, and how both sit against every other frame bags product we track.
Weight checked against the manufacturer on 25 August 2026 — see the source. The price above has not.

How the Joey Downtube Bag 2L 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 136g the Joey Downtube Bag 2L is lighter than 13 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 $55 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.
