Salsa Warbird frame geometry, drawn to scale

Every tube angle and length below is from the published chart, not an illustration. The front triangle area is the number that decides which frame bags fit — and it changes a lot across sizes.

What this frame gives a loaded bike

Chainstay length is the gap between the seat tube and the rear axle, which a rack, panniers and your heels all have to share. Bottom bracket drop is how far the cranks sit below the axles. Both are compared against the median across every current frame we hold.

430mm chainstays, 5mm shorter than the 435mm median across the 65 current frames here. Bottom bracket drop 70mm, close to the 70mm median. The fork publishes cargo mounts, and the frame publishes up to 3 bottle or accessory positions. A rear rack bolts straight on. Widest published tire 51mm on 650b / 27.5in, 45mm on 700c / 29in. It takes a dropper post.

Every figure above is the manufacturer's, computed against the rest of the database. It says what the frame allows, not how it feels — nobody here has ridden it.

What it can carry

Mount provision and clearance, as Salsa publishes it.

Fork mounts
Fork bottle mounts: two; low-rider rack mounts; fender mounts

Bottom bracket height

Roughly 301mm off the ground. Salsa doesn't publish this directly — we derive it from their BB drop and a typical 74.2cm tire diameter, so treat it as indicative rather than exact. It changes with the tire you fit. Lower means more stable and more pedal strikes; higher means the opposite.

Source — Salsa's own geometry chart: https://www.salsacycles.com/products/2025-warbird-c-grx-820-2x — checked 2026-08-16. A dash means the figure isn't published; we leave it blank rather than estimate.

Note: Salsa still lists Warbird, but Flyway appears to be the new fifth-generation carbon gravel platform. Collection prices include 'From' and sale/current listing prices.

How the Warbird compares

Against the frames people actually cross-shop it with — both charts held together, on the specs that decide what the bike carries.

Questions people ask about this frame

Answered from what Salsa publish. Where they publish nothing, that is what it says.

Does the Warbird take fork cargo cages?

Yes — 2 cages. Salsa publish cargo-cage mounts on the fork, one set per leg.

What is the widest tyre the Warbird takes?

51mm on 650b / 27.5in. Across the wheel sizes Salsa publish: 45mm on 700c / 29in, 51mm on 650b / 27.5in. Those are frame figures, not the fork's — forks are routinely cut for more rubber than the rear triangle.

Will a seat pack work on the Warbird?

The dropper is the problem, not the pack. This frame publishes dropper routing, and a dropper and a seat pack want the same space — fitting one rules out almost every strap-on seat pack and leaves rail-mounted bags at a fraction of the volume. Run a rack or a saddle-rail bag if you want both.

Frame bag fit is calculated from Salsa's published geometry, so it's as reliable as their chart. Seat packs and handlebar rolls depend on your exposed seatpost and bar width, which no geometry table lists — the bag finder covers those once you add your own measurements.
