Surly Straggler 700c 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.
425-430mm chainstays, 7.5mm shorter than the 435mm median across the 65 current frames here. Bottom bracket drop 72mm, 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 50mm on 700c / 29in. Surly publishes no dropper routing for this frame.
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 Surly publishes it.
Fitting fenders costs 3mm of that.
Surly's wording: “700c x 50mm without fenders; 700c x 47mm with fenders”
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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 54cm | 565 | 540 | 791.7 | 107 | 549.2 | 396.3 | 425 | 1016.5 | 72 | 72° | 73° |
| 56cm | 580 | 560 | 809.4 | 121 | 567.3 | 400.7 | 430 | 1031.9 | 72 | 72° | 72.5° |

| 60cm | 610 | 600 | 846.1 | 165 | 609.1 | 412.1 | 430 | 1056.8 | 72 | 72° | 72° |

Bottom bracket height
Roughly 303mm off the ground. Surly 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.

How the Straggler 700c 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 Surly publish. Where they publish nothing, that is what it says.
Does the Straggler 700c take fork cargo cages?
Rack mounts, not cage mounts. The fork mounts Surly publish are for racks or fenders, and a lowrider eyelet won't take a cargo cage. That doesn't rule cages out — it means nobody has said.
What is the widest tyre the Straggler 700c takes?
50mm on 700c / 29in. That is the frame figure rather than the fork's, and it is what limits a loaded bike.
Will a seat pack work on the Straggler 700c?
A seat pack is the straightforward answer here. Surly publish no dropper routing for this frame, so nothing is competing with the pack for seatpost length.
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 595mm effective top tube and 580mm seat tube. 16 fit.
Frame bag fit is calculated from Surly'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.
