Specialized Fuse Comp 29 Geometry & Bikepacking Bag Fit2022
Discontinued. Specialized no longer lists the Fuse Comp 29. It's here because these frames stay in circulation second-hand and the geometry is still what you need to pick bags — but you won't find one new.
Specialized Fuse Comp 29 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.
420mm chainstays, 15mm shorter than the 435mm median across the 65 current frames here. Bottom bracket drop 60mm, 10mm less than the 70mm median. Specialized publishes no fork cargo mounts, and no frame bottle positions are published. Specialized publishes no rear rack answer, which is not the same as no — but it is not something to buy a rack on. 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 Specialized publishes it.
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 | 579 | 340 | 727 | 95 | 625 | 400 | 420-435 | 1122 | 60 | 66.5° | 74° |
| S | 599 | 375 | 747 | 95 | 625 | 420 | 420-435 | 1142 | 60 | 66.5° | 74° |
| M | 619 | 410 | 750 | 95 | 625 | 440 | 420-435 | 1162 | 60 | 66.5° | 74° |
| L | 643 | 455 | 754 | 110 | 639 | 460 | 420-435 | 1188 | 60 | 66.5° | 74° |

Bottom bracket height
Roughly 315mm off the ground. Specialized 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 — Specialized's own geometry chart: https://www.specialized.com/us/en/fuse-comp-29/p/199945 — checked 2026-08-18. A dash means the figure isn't published; we leave it blank rather than estimate.
Note: 2022 Fuse Comp 29; no later Fuse Comp 29 listing exists on Specialized’s site, so this is stored as discontinued. Geometry is in millimetres and degrees, chainstay as the published adjustable-dropout range. No frame tire maximum is stored: Specialized publishes the fitted size rather than a frame limit — “while this Fuse's 29x2.6 tires give it a precise, nimble feel, the M4 aluminum frame is also compatible with 27.5+ wheels and tires.” — and a fitted tire is not a maximum. Ships with a dropper: “TranzX Dropper, 34.9mm, XS-S: 100mm, M: 125mm, L-XL: 150mm”
Questions people ask about this frame
Answered from what Specialized publish. Where they publish nothing, that is what it says.
Does the Fuse Comp 29 take fork cargo cages?
Not published. Specialized don't state any fork mount provision for this frame. That isn't the same as it having none, and we won't guess from a photo.
What is the widest tyre the Fuse Comp 29 takes?
Not published in a form we can read. Specialized don't publish a maximum tyre width for this frame.
Will a seat pack work on the Fuse Comp 29?
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 619mm effective top tube and 410mm seat tube. 13 fit.
Read these as conservative. This size has a steeply sloping top tube — the seat tube is only 66% of the effective top tube. Bag makers publish a minimum seat tube length assuming a roughly level top tube, so on a frame like this the comparison understates how much room you actually have. The front triangle here is about 1220 cm², which is the number that actually decides what fits. Several bags marked unlikely below will physically fit. Half-frame bags don't depend on seat tube length at all.
Frame bag fit is calculated from Specialized'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.
