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 Most makers do not publish it, so I assume 15 mm and add 6 mm to the band, which on its own is enough to hold an answer at "probably" rather than "fits".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 table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The L (515) 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.
The maker's cockpit
No stock cockpit I can name, so every size is solved on a generic stem and bar unless you choose one on the sheet.Tavelo AVRO Gen-1 CockpitVendor-listedstem -10 · reach 77 · drop 130 · clamp 36.4 · lengths 80-130 · widths 360-420

How I read the maker's table
site built on Ueeshop, assets hosted at ueeshop.ly200-cdn.com). The product page's "Description" tab is empty and the "Geometry" tab is one image (diagram + table); no HTML/PDF table exists, so every number in sizes[] was read from the image by the collector at native resolution. Table columns are XS/S/M/L/XL/XXL; the store's size dropdown is named by row A only (430/460/490/515/540/570) and the Specification tab writes them "XS (430), S(460), M(490), L(515), XL(540), XXL(570)" - size_label uses that naming. STACK DATUM: the diagram draws STACK vertically from the BB centre to a horizontal reference line at the top of the head tube (no bar or headset cover drawn) and REACH horizontally from the BB centre to the same head-tube-top point - conventional frame stack/reach, not to the bar. Standover datum (where along the top tube) is not stated. Angles are published to 0.1 deg and trail to 0.01 mm exactly as shown; nothing was rounded. Trail row is labelled "FORK TRAIL" and is maker-published (kept); back-solving trail with E and K gives an implied wheel radius of about 361.5 mm (roughly 700c x 50 mm) for every size, so the maker's trail assumes a large gravel tyre (assumption not stated on the page). integrated_cockpit is true because the frame is fully internally routed and the maker pairs it only with its one-piece AVRO cockpits; the frameset itself ships bar-less, so stock_stem_length / stock_bar_width are null. MODEL YEAR: not stated anywhere on the page; footer copyright 2024; product photos uploaded 2026-03-31 (CDN path 2603/31), geometry image uploaded 2026-04-03 (CDN path 2604/03), meta description still reads "A brand-new gradual control product will be launched soon" - i.e. a 2026 launch, but no model year is printed so the field is left null. Category taken from the brief (gravel); the maker's own copy says "GROW - Aero Unleashed" and "Aerodynamic gravel performance, born to go faster" (an aero gravel bike). No aggregator was consulted; Panda Podium was not used for this file.
