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 Most makers do not publish it, so I assume 15 mm and add 6 mm to the band, which on its own is enough to hold an answer at "probably" rather than "fits".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.The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The L/54 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.Generic stem and barAssumedNo bar is listed for this frame.
In the maker's words
Kept whole, as I read it off voicevelo.com.Frameset sold as a frame + fork only on the maker's site (product page: the only option is the colourway - VO1 Mystical Purple, VO2 Abyss Black at USD 1699; VH1 Champion Yellow, VH2 Combativity Orange at USD 1399).
Cockpit and seatpost, in the maker's words · 342 words
Frameset sold as a frame + fork only on the maker's site (product page: the only option is the colourway - VO1 Mystical Purple, VO2 Abyss Black at USD 1699; VH1 Champion Yellow, VH2 Combativity Orange at USD 1399). No bar, stem, stem length, bar width, spacer stack, headset cover height or seatpost offset is published for the ECHO on voicevelo.com. The page's weight list includes 'Deep-V seatpost: 155g' alongside the frame and fork weights, which implies an ECHO seatpost is part of the kit, but the page never says what is included. The separate Deep-V seatpost product on voicevelo.com (https://voicevelo.com/products/deep-v-seatpost) is a ROUND post: length 400 mm, diameter 27.2 or 30.9 mm, offset 5 mm, 160 g +/-5 (27.2) / 170 g +/-5 (30.9), titanium bolts - it is described as 'designed for off-road riding' and does not obviously match the 155 g aero-profile post fitted in the ECHO photos, so treat the ECHO seatpost shape/offset as NOT published. Cockpit: the page says 'ECHO + R1 - The Perfect Pair ... Unified aerodynamic language between frame and bar' and the studio photos show a one-piece bar whose stem cap reads 'VFV R1'; the maker's site has NO R1 product page (site search and the VFV Components collection list only BASS crank, Deep-V seatpost, Fast Catch System, GA5450 wheelset and XC1 MTB bar as of 2026-08-29). Routing is 'FSA ACR Internal Cable Routing' / 'Fully internal cable routing (compatible with mechanical/electronic groupsets)', so the frame takes ACR-standard bars and stems, i.e. a two-piece cockpit is possible. Distributor cross-reference only (Panda Podium Store API, NOT the maker): 'VoiceVelo VFV R1 Integrated Handlebar' one-piece T800/T1000, stem angle -10 deg, flare 11 deg, hood rise 10 mm, 320 g (400/100 mm), and 'VoiceVelo VFV ADV Carbon Stem' 70-140 mm, -12 deg, 1 1/8 in steerer, 31.8 mm clamp, listed as 'Clean fit on VFV G Major and ECHO framesets'; the same distributor describes the ECHO frameset as fully integrated with electronic routing. None of those cockpit numbers appear on voicevelo.com, so integrated_cockpit is left null.

How I read the maker's table
Numbers were read from the image by the collector (page fetched 2026-08-29, HTTP 200); the plain-text description carries no geometry. Rows in the image, letter-coded to a frame diagram: A Seat tube, B Stack, C Reach, D Effective top tube, E Head tube length, F Head angle, G Standover Height, H BB drop, I Trail, J Effective seat tube angle, K Chainstay, L Front center, M Wheelbase, N Fork offset, O Fork length. STACK DATUM: diagram draws B as the vertical from the bottom bracket centre to the top of the head tube and C as the horizontal from the BB vertical to the same point (conventional stack/reach); nothing suggests a headset-cap datum. STANDOVER: row G, drawn as a vertical at roughly mid top tube, datum not stated (assumed ground to top tube). SIZE NAMES: 'S/49', 'M/52', 'L/54', 'XL/56' - the number is a nominal cm size, not the seat tube length (seat tubes are 465/490/520/545 mm). Recommended rider height printed above the table: S 158-168 cm, M 162-174, L 173-183, XL 178-188. All four sizes are one frame geometry for both variants: 'Lightweight VO Series' (VO1/VO2) and 'Standard VH Series' (VH1/VH2) share the single table; the page says 'Available in 4 sizes'. Other page facts: weight (painted M-size frame, without hardware) lightweight version frame 975 g / fork 507 g, standard version frame 1100 g / fork 526 g; head tube stiffness 105.78 Nm, BB stiffness 174.6 Nm; T1100 high-modulus carbon in the head tube; T47A threaded BB (asymmetric); UDH; bottom-mounted Di2 battery compartment; max chainring 56T; max tyre 34C; 'Deeper Head Tube: takes advantage of updated UCI rules (8:1 tube ratio)'. MODEL YEAR: none stated by the maker; the geometry and product images sit under CDN upload paths 2602/06 and 2602/07 (2026-02-06/07) and the lifestyle photos under 2603/06, so the frame launched around Feb-Mar 2026 - model_year left null rather than guessed. Distributor cross-reference (Panda Podium Store API, one request, index only): lists 'Voicevelo VFV ECHO Aero Road Bike Frameset' with T1100 + T800 (VO) / T800 (VH) carbon and weights VO 975 g / VH 1100 g 'Size M/52, unpainted, no hardware' - note the maker says PAINTED for the same numbers; the maker's page wins for this record. No aggregator was consulted.
