Sonder CaminoGeometry & Bikepacking Bag Fit2026
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.
434mm chainstays, about the median for the 66 current frames here. Bottom bracket drop 73mm, close to the 70mm median. The fork publishes cargo mounts, and the frame publishes bottle or accessory mounts. A rear rack bolts straight on. Widest published tire 56mm on 650b / 27.5in, 50mm 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 Sonder publishes it.
Sonder's wording: “700 x 50mm or 650b x 2.2” tyre clearance”
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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| XS | 521.8 | 430 | 695.4 | 130 | 545.2 | 370 | 434 | 1034.1 | 73 | 69° | 74.5° |
| S | 536.4 | 460 | 765.9 | 150 | 563.9 | 380 | 434 | 1050.8 | 73 | 69° | 74.5° |
| M | 562.1 | 490 | 773 | 170 | 582.6 | 395 | 434 | 1073 | 73 | 69° | 74° |
| L | 592.4 | 520 | 812.4 | 190 | 601.2 | 420 | 434 | 1105.2 | 73 | 69° | 74° |
| XL | 625.3 | 550 | 815 | 205 | 615 | 440 | 434 | 1131 | 73 | 69° | 73° |
Bottom bracket height
Roughly 302mm off the ground. Sonderdoesn'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 — Sonder's own geometry chart: https://alpkit.com/products/sonder-camino-al-grx2 — checked 2026-08-18. A dash means the figure isn't published; we leave it blank rather than estimate.
Note: Camino Al GRX2 complete bike. The geometry chart labels TT as top tube and it is stored as effective top tube; XS is published as “521.8 (Curved)” and the parenthetical is dropped. Alpkit’s page carries two different clearance figures — feature copy says 650b x 2.1”, the frame spec says 2.2” — and the frame spec is the one stored. Price is Alpkit’s, in GBP. Sonder on droppers: “The Camino also has routing for a dropper seatpost.” Size XS has no seat tube bottle bosses.
Which frame bags fit
Every frame bag we track, checked against this frame's published geometry. Pick your size.
Checking 19 frame bags against a 562.1mm effective top tube and 490mm seat tube. 19 fit.
Frame bag fit is calculated from Sonder'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.
