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 Most makers do not publish it, so I assume 10 mm and add 6 mm to the band beside every answer.
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 hands sit than your saddle. On a riser bar I count the bar's rise, so the drop is that much less than it is to the clamp.
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.

In the maker's words
Kept whole, as I read it off parduscycle.com.The complete bike ships the MVMT M-SILVER B-TYPE carbon bar ("全隐藏内走线" fully hidden internal routing, bar reach 85 mm, drop 130 mm; stem lengths 100/100/110/110/120 and bar widths 380/380/400/420/420 by size, as the table prints).

SOURCE: parduscycle.com is Pardus's own Chinese-language site (PARDUS 瑞豹, the brand's home market site). Source: html table (maker's own Chinese-language site parduscycle.com, product page section "几何参数" (geometry), an HTML table)
How I read the maker's table
its product pages ("Hightxq.aspx?t=...&id=...") carry the geometry as an HTML table under "几何参数" (geometry parameters). The European site pardusbicycle.com, which the other Pardus files cite, lists only the Gomera TT, Robin Evo, Robin Sport, Spark Evo and Uragano Sport (its /bikes/ page, fetched 22 Oct 2026), so this frame is on the Chinese site only. The page sells complete bikes; the table is the frame's. Page "进阶款综合公路车" (advanced all-round road bike), product ROBIN RS, sizes XS/S/M/L/XL. Its numbers are those Bike Insights files as the 2021 Robin EVO (citing an earlier parduscycle.com page) and as RobinRS 2023: the second-generation Robin geometry, kept as the Robin RS; the held pardus-robin-evo is the third-generation Robin EVO (2024), a different table. Spec (技术参数): frame ROBIN RS, HS-EPS carbon, 12x142mm thru axle, flat mount disc; fork ROBIN RS, HS-HPT carbon, 12x100mm thru axle, flat mount; bar MVMT M-SILVER B-TYPE carbon, fully hidden routing, 85mm reach, 130mm drop; seatpost MVMT M-SILVER carbon, "-15mm or 0mm offset", 350mm x 27.2mm; Shimano 105 R7000/R7020 2x11, 50-34T, 11-28T; PARDUS PW5 DB wheels. Crank 167.5/170/170/172.5/172.5; seatpost offset -15 every size (the post's setback written with a minus sign). Rows as printed (Chinese labels, translated): 尺码 size; 前伸量 reach (R); 堆高 stack (S); 堆高/前伸量 stack/reach ratio (STR, not in the schema); 跨高 standover; 上管水平长度 "top tube, horizontal" (B, top_tube_effective); 头管角度 head angle (C); 立管角度 seat angle (D); 轴距 wheelbase (E); 后下叉长度 chainstay (F); 前轴距 front centre (G); 中轴下沉量 BB drop (H); 立管长度 seat tube length (I); 头管长度 head tube length (J); 前叉偏移量 fork offset (K); 前叉长度 fork length (L, not in the schema); 拖距 trail (kept as printed; no tyre named); 把立长度 stem length and 车把宽 bar width of the complete bike per size (stock_stem_length, stock_bar_width); 曲柄长度 crank length and 座杆偏移 seatpost offset (not in the schema). STACK DATUM: the page draws no stack; on this site the SPKG4 EVO table prints stacks 18 mm higher and reaches 6 mm shorter than the same frame on the European site (to a headset cover, it seems), while its Robin EVO table matches the European one, so no datum is assumed (stack_datum null).
