Stack and reach
How high and how far forward the top of the head tube is, from the bottom bracket. They are the two numbers that decide whether a frame can be set up like yours.
BB, or bottom bracket
The axle your cranks turn on, in the middle of the frame. Every number on this site is measured from it, because it is the one point that sits in the same place on every bike.
Headset cover
The little cap on top of the head tube, under your spacers. Most makers do not publish it, so I assume 15 mm and add 6 mm to the band, which on its own is enough to hold an answer at "probably" rather than "fits".
Stem clamp, and its centre
The collar on the steerer that your stem bolts to. I need the middle of it. Where a maker gives only the height, I assume halfway up and say so on the answer.
Steerer
The tube coming up out of the fork. The cover, the spacers and the stem all sit on it, and it is the thing a mechanic cuts to length.
Bar reach
How far forward the hoods sit from the middle of the bar. Two bars on the same stem can put your hands 20 mm apart, which is why I ask.
Setback
How far your saddle sits behind the bottom bracket.
Drop
How much lower your bar is than your saddle.
Rails, and the rail centre
The two rods under your saddle, and the middle of the straight part of them. That midpoint is the point I use, because it is the one you can find with a tape.
The band
How far out I could be, in millimetres, and why. It is a straight sum of everything I had to assume rather than a clever average, so it errs wide on purpose.
wb, stand, trail
Wheelbase, standover and trail: how long the bike is, how high the top tube is where you straddle it, and how steady the steering feels. I show them against your bike, and I leave them out when the maker does not publish them.
est.
Estimated: a number I worked out rather than read off the maker's table. Anything marked this way can move if the maker publishes the real one.

Geometry, every size, from the maker's table
The tinted row is the size drawn beside it. Press a size to draw it.| Size | Stack (mm) | Reach (mm) | Head angle (deg) | Seat angle (deg) | Head tube (mm) | Chainstay (mm) | Wheelbase (mm) | Standover (mm) |

The L / 510 drawn to scale from the table, with no build on it. Stack and reach run from the bottom bracket to the top of the head tube; every size is solved from those two. One square is 100 mm.

Cockpit and seatpost, in the maker's words · 378 words
INTEGRATED one-piece cockpit: TAVELO AVRO Gen-1 (brand page https://tavelo.cc/products/avro-gen-1-cockpit, USD 300). On tavelo.cc the Arow SL Plaid frameset (USD 2,150) lists Frame / Fork / Seat post under Frameset in its Specification tab and the cockpit is sold as a separate Frequently Bought Together add-on (bundle shown as frameset USD 2,080 + AVRO Gen-1 USD 300, or + AVRO RISE USD 350), so on the brand site the bar is NOT part of the frameset price; the distributor Panda Podium lists its Arow SL package as Frame, Fork, Seatpost, Saddle Clamp, Thru Axles, Headset and Spacers, BB, Integrated handlebar. AVRO Gen-1 spec (brand spec image on the cockpit page, two versions of the same table): W1 hood-to-hood 360 / 380 / 400 / 420 mm; W2 drop-to-drop 380 / 400 / 420 / 440 mm; reach 77 mm; drop 130 mm; drop flare 2.6 deg; stem angle 10 deg (diagram shows 80 deg to the steerer, i.e. -10 deg); stack (stem clamp height) 36.4 mm; stem lengths 80 / 90 / 100 / 110 / 120 / 130 / 140 mm (the older version of the spec image stops at 130 and says 330 g, the newer one goes to 140 and says 340 g, both for 400 x 110); brand configurator offers every width x every length 80-140 (28 combinations). Alternative cockpit on the same bundle: AVRO RISE riser cockpit, 340 / 360 / 380 / 400 mm x 80-140 mm. The brand page has no per-size default cockpit, so stock_stem_length and stock_bar_width are null. Spacers: the brand page does not publish spacer heights or a maximum stack; Panda Podium says the handlebar ships with computer holder, spacers and top cap, and that AROW framesets come pre-equipped with a Tavelo-compatible headset adapter (a separate Top Cap for Cockpit is USD 15 on tavelo.cc). Headset: FSA (32.8-41.8 mm to 34.1-46.9 mm) as written on the spec tab. Seatpost: Arow aero seat post, Toray T800, spec tab reads verbatim "5mm, 7*7 or 7*9 wedge" (the 5 mm is most likely the offset but the page does not say so; 7x7 / 7x9 are the saddle-rail clamp wedges), 113 g without saddle clamp; no other length or offset published. Fork length (axle to crown, row I) 370 mm all sizes.

How I read the maker's table
the identical geometry image is used on https://tavelo.cc/products/tavelo-arow-sl-neo-black (checked) and the Arow Race pages share the same frame. The chart has no visible units or title beyond the lettered diagram; all lengths taken as mm, angles in degrees. STACK DATUM: drawn from the BB centre vertically to the top of the head tube (the frame, not the headset cap) as far as the diagram shows; not stated in words. TRAIL is published by the brand (FORK TRAIL row) and is consistent with the head angle and 45 mm offset for a roughly 700x28 wheel. SIZES: the chart carries six sizes XS-XXL, but the SL Plaid and SL Neo Black listings on tavelo.cc offer only XS(420), S(450), M(480), L(510) (Panda Podium likewise lists the SL in XS-L and the Arow Race in XS-XXL); XL and XXL rows are kept because the maker publishes them on the same chart. MODEL YEAR: not stated anywhere on the page; the geometry image was uploaded 2025-03-06 (CDN path 2503/06), product photos 2024-07-12, copyright footer 2024, Panda Podium SL listing images 2024-05; left null. FRAME FACTS: SL = Ultralight Edition, Toray T1100 frame 710 g raw size XS (Race version T800, 820 g), fork T800 355 g raw, press-fit BB86, 12x100 / 12x142 thru axles, flat mount, max tyre 32 mm, internal routing for electronic groups only (Panda Podium: no mechanical), UCI approved per Panda Podium. Panda Podium (Store API, id 8930 and 8902) used only to confirm the size list and package contents, no numbers taken from it.
