Bombtrack Beyond Geometry & Bikepacking Bag Fit2026
The only link we hold for this frame is the geometry document itself, which is not a page you can buy from.
Bombtrack Beyond 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.
425-455mm chainstays, 5mm longer than the 435mm median across the 65 current frames here. Bottom bracket drop 55-70mm, 8mm less than the 70mm median. The fork publishes cargo mounts, and no frame bottle positions are published. A rear rack bolts straight on. Widest published tire 53mm, the same on 700c / 29in and 650b / 27.5in.
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 Bombtrack publishes it.
- XS - S 27.5'' x 2.1''
Bombtrack's wording: “Frame max tire clearance w/o fender: XS - S 27.5'' x 2.1'' M - XL 29'' x 2.1''”
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 | 494 | 400 | 727 | 100 | 538 | 349 | 425 | 1000 | 55 | 70° | 75° |
| S | 522 | 440 | 761 | 130 | 568 | 364 | 425 | 1021 | 55 | 70.5° | 74.5° |
| M | 558 | 480 | 802 | 150 | 604 | 379 | 455 | 1065 | 70 | 71° | 73.5° |
| L | 590 | 520 | 842 | 190 | 646 | 392 | 455 | 1082 | 70 | 72° | 73° |
| XL | 623 | 560 | 873 | 220 | 675 | 411 | 455 | 1109 | 70 | 72° | 72.5° |
Bottom bracket height
Roughly 305–320mm off the ground. Bombtrack 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 — Bombtrack's own geometry chart: https://cdn.shopify.com/s/files/1/0951/5384/8662/files/Geometry_frame_BEYOND.pdf?v=1770917647 — checked 2026-08-18. A dash means the figure isn't published; we leave it blank rather than estimate.
Note: Geometry from Bombtrack’s own BEYOND chart. Wheel size is set by frame size: XS-S are 27.5in, M-XL are 29in. priceFrom is the Beyond 1 complete-bike price in EUR from bombtrack.com. Bombtrack describes the frame as having “a multitude of bottle and rack mounting options” without stating a count, so the bottle field is left empty.
How the Beyond compares
Against the frame 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 Bombtrack publish. Where they publish nothing, that is what it says.
Does the Beyond take fork cargo cages?
Yes. Bombtrack 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 Beyond takes?
53mm on 700c / 29in. Across the wheel sizes Bombtrack publish: 53mm on 700c / 29in, 53mm 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 Beyond?
Not published. Bombtrack don't state dropper compatibility for this frame, so we can't tell you whether a dropper would compete with a seat pack on it.
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 558mm effective top tube and 480mm seat tube. 16 fit.
Frame bag fit is calculated from Bombtrack'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.
