Rodeo Labs Flaanimal 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.
435mm chainstays, about the median for the 65 current frames here. Bottom bracket drop 70-75mm, close to the 70mm median. The fork publishes cargo mounts, and the frame publishes up to 2 bottle or accessory positions. A rear rack bolts straight on. Widest published tire 60mm, the same on 700c / 29in and 650b / 27.5in. 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 Rodeo Labs publishes it.
Rodeo Labs's wording: “Tire clearance 650b | Max width: 2.4″ / 60mm with Spork 4. 2.2″ / 56mm with Spork 3 | Min. recommended width: 54mm | Varies by tire / rim / conditions; Tire clearance 700c | Max width: 2.4″ / 60mm with Spork 4. 2.2″ / 56mm with Spork 3 | Min. recommended width: 32mm | Varies by tire / rim / conditions”
Geometry
All figures in millimeters except angles. Effective top tube and seat tube are the two that decide frame bag fit.
| Size | Eff. top tube | Seat tube | Standover | Head tube | Stack | Reach | Chainstay | Wheelbase | BB drop | Head angle | Seat angle |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 49 cm | 510 | 445 | 750 | 100 | 532 | 377 | 435-465 | 1025 (variable) | 75 | 70° | 76° |
| 52 cm | 528 | 473 | 774 | 122 | 553 | 385 | 435-465 | 1041 (variable) | 75 | 70° | 75.5° |
| 54 cm | 543 | 493 | 794 | 142 | 570 | 395 | 435-465 | 1058 (variable) | 73 | 70° | 75.5° |
| 56 cm | 564 | 513 | 812 | 162 | 589 | 406 | 435-465 | 1076 (variable) | 73 | 70° | 75° |
| 58 cm | 580 | 533 | 833 | 184 | 606 | 418 | 435-465 | 1095 (variable) | 70 | 70° | 75° |
| 61 cm | 605 | 563 | 861 | 212 | 633 | 436 | 435-465 | 1123 (variable) | 70 | 70° | 75° |
Bottom bracket height
Roughly 300–305mm off the ground. Rodeo Labs doesn't publish this directly — we derive it from their BB drop and a typical 75cm 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 — Rodeo Labs's own geometry chart: https://rodeo-labs.com/infosheet/flaanimal-6-0-steel-geometry/ — checked 2026-08-18. A dash means the figure isn't published; we leave it blank rather than estimate.
Note: Geometry chart states dimensions are listed in millimeters and degrees unless otherwise indicated. Product base price is for Frame, Fork, Axles, Seatpost collar, Routing Hardware, Slider / Dropout hardware; complete build kits are also offered. Chainstay range uses the published 435mm chart value plus the manufacturer-published 30mm slider range and manual statement that stays extend up to 465mm. Wheelbase is returned with the maker's '(variable)' wording rather than computing a range. Rodeo routes the dropper internally, through the BB area via the Bowtie pass-through.
How the Flaanimal 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 Rodeo Labs publish. Where they publish nothing, that is what it says.
Does the Flaanimal take fork cargo cages?
Yes. Rodeo Labs publish cargo-cage mounts on the fork, but the wording does not give a count we can stand behind, so we're not going to put a number on it.
What is the widest tyre the Flaanimal takes?
60mm on 700c / 29in. Across the wheel sizes Rodeo Labs publish: 60mm on 700c / 29in, 60mm 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 Flaanimal?
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.
Which frame bags fit
Every frame bag we track, checked against this frame's published geometry. Pick your size.
Checking 16 frame bags against a 564mm effective top tube and 513mm seat tube. 16 fit.
Frame bag fit is calculated from Rodeo Labs'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.
