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.
425mm chainstays, 10mm shorter than the 435mm median across the 64 current frames here. Bottom bracket drop 75mm, 5mm more than the 70mm median. Focus publishes no fork cargo mounts, and the frame publishes up to 3 bottle or accessory positions. A rear rack bolts straight on. Widest published tire 48mm on 700c / 29in. On droppers Focus says: "Yes, technically you can add 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 Focus publishes it.
Focus's wording: “Frame 48mm on the 6. series, 45mm on the 8. series; fork 53mm. Not 650b compatible.”
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 | 506 | 440 | 757 | 105 | 556 | 365 | 425 | 1015 | 75 | 70° | 74.5° |
| S | 531 | 470 | 778 | 120 | 572 | 380 | 425 | 1031 | 75 | 70.5° | 74° |
| M | 548 | 500 | 802 | 140 | 591 | 385 | 425 | 1042 | 75 | 70.5° | 73.5° |
| L | 564 | 530 | 825 | 160 | 610 | 395 | 425 | 1059 | 75 | 70.5° | 73.5° |
| XL | 593 | 560 | 852 | 190 | 638 | 410 | 425 | 1084 | 75 | 70.5° | 73° |
Bottom bracket height
Roughly 300mm off the ground. Focusdoesn'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 — Focus's own geometry chart: https://www.focus-bikes.com/nl_en/atlas-6-7 — checked 2026-08-18. A dash means the figure isn't published; we leave it blank rather than estimate.
Note: MY26 Atlas 6. series aluminium chart; Focus publishes a separate chart for the 8. series carbon bikes. Price is EUR from the manufacturer page. Fork mounts are left empty because Focus’s answer is about a front rack, not cargo cages: “Yes, you can. The thread is a bonded alloy piece to ensure the safe usage of a front rack. The maximum load on the fork is 3 kg per side.” Focus on droppers: “Yes, technically you can add a dropper post.”
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 548mm effective top tube and 500mm seat tube. 19 fit.
Frame bag fit is calculated from Focus'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.
