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) |
|---|---|---|---|---|---|---|---|---|
| 46 / 460 | 502.6 | 371 | 71 | 74.5 | 105 | 410 | 971.4 | 733.9 |
| 49 / 490 | 505.4 | 385.1 | 71 | 74.5 | 108 | 410 | 986.6 | 753.6 |
| 52 / 520 | 521.2 | 390.8 | 72 | 74 | 121 | 410 | 988.7 | 772 |

The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The 54 / 540 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.

In the maker's words
Kept whole, as I read it off lightcarbon.com.INTEGRATED one-piece bar/stem: LightCarbon HBR17 (Toray T1000 + T800 + M40JB), included in the frameset ("Frame + fork + seat post + clamp + headset bearings + spacers + thru-axles + HBR17 integrated handlebar").
Cockpit and seatpost, in the maker's words · 329 words
INTEGRATED one-piece bar/stem: LightCarbon HBR17 (Toray T1000 + T800 + M40JB), included in the frameset ("Frame + fork + seat post + clamp + headset bearings + spacers + thru-axles + HBR17 integrated handlebar"). Widths 360 / 380 / 400 / 420 mm (top, centre to centre); stem lengths 80 / 90 / 100 / 110 / 120 / 130 mm. The frame page lists both ranges without tying a width or length to a frame size and states no per-size default, so stock_stem_length and stock_bar_width are null. HBR17 page (https://www.lightcarbon.com/ultra-light-and-aero-carbon-road-integrated-handlebar_p257.html): stem angle -7 deg; bar reach 75 mm; bar drop 125 mm; "15mm Flare Design": 15 mm flare each side, so drop width is 390 / 410 / 430 / 450 mm for the 360 / 380 / 400 / 420 tops (a bullet elsewhere on the same page says "12 degree flare drop bar"); "8mm lift" at the tops (maker says it "saves you a 10mm spacer" versus a flat bar); steerer 28.6 mm (1 1/8 in); "Stem height spacer 2*5mm + 2*10mm" supplied (maximum spacer stack NOT published; stem clamp height NOT published); clamp torque 6 N.m; weight 295 g +/-4% (360x80), 305 (380x80), 310 (380x100), 315 (400x100), 320 (420x100); package adds computer holder (Garmin / Wahoo / Bryton / Cateye), stem cover, GoPro holder, titanium stem bolts. Headset: straight 1 1/2 in head tube, upper 52 mm / lower 52 mm bearings, included. Seatpost: LightCarbon carbon post, default 20 mm offset with 7x7 mm rail clamp; 0 mm offset with 7x9 mm clamp optional at order time; 160 g +/-10 g; post length not published; seatpost insert length per size 130 / 150 / 170 / 190 / 210 / 230 mm (46-58). A sibling listing (p241, "...Frameset With Stem") sells the same LCR017-D frame with a separate stem instead of the HBR17. HBR17 fit requirement stated by the maker: head tube upper inner diameter 52.1 mm, depth 8.7 mm, fork steerer OD 28.6 mm.

How I read the maker's table
the geometry diagram image next to it (/js/htmledit/kindeditor/attached/20240227/20240227162028_64274.jpg, path dated 2024-02-27) was not stored or used. STACK/REACH DATUM: the table says only "STACK" and "REACH" with no datum wording; ASSUMED to be bottom bracket centre to top of head tube (the HBR17 is a separate part and not part of stack). SIZE NAMES: the spec table names sizes 46, 49, 52, 54, 56, 58 (cm) and the geometry columns are headed 460 / 490 / 520 / 540 / 560 / 580, but the published seat tube lengths are 460 / 480 / 500 / 522 / 542 / 560, so the column header is a nominal size, not the seat tube; size_label carries both. Column mapping: top_tube_effective = "TOP TUBE LENGTH, HORIZONTAL"; standover = "BIKE STANDOVER HEIGHT(700C*32C)"; fork_offset = "FORK RAKE/OFFSET"; front_centre = "FRONT CENTER"; trail = "TRAIL" (published by the maker, not derived). Published but outside the schema: BB height 278 mm all sizes; fork length (full) 368 mm all sizes; seatpost insert length 130 / 150 / 170 / 190 / 210 / 230 mm; rider height reference 156-165 / 166-172 / 173-179 / 180-186 / 187-193 / 194-199 cm ("for reference only"). MODEL YEAR: not stated anywhere on the page (site copyright 2026; geometry image path dated 2024-02-27), so null. Frame: Toray T700 + T800 + T1000, claimed weight +/-30 g of 850 (46) / 850 (49) / 870 (52) / 890 (54) / 910 (56) / 945 (58) g, UCI approved, T47 threaded BB (68 mm, P1.0), flat mount 140 / 160, 12x100 / 12x142 thru axles, UDH, max tyre 700x32C, fork 390 g +/-15 g, ISO 4210, 2 year warranty. Category recorded as climbing road as requested (sub-900 g frame, 32 mm clearance).
