The LightCarbon LCG072 (LCR72) is an aero race gravel frameset with aero seatpost, T47 bottom bracket, UDH, downtube storage and electronic-only shifting, sold as a frameset kit for $719 with integrated bar, seatpost, headset, axles and storage bag. Owners report a light frame (claimed 1100 g, measured 1280 g in size M) and good real-world tyre clearance (50 mm 1x, about 45 mm 2x), but flag long and variable lead times, a proprietary seatpost with saddle-clamp concerns, and no logo-free option without paying $250–300 for custom paint or decals.
Pros
- Lightweight build: 8.46 kg complete including computer mount, with frame measured at 1280 g and fork at 454 g1
- Good value: $719 frameset kit includes integrated bar, seatpost, headset, axles and storage bag; complete build cost about $2,400–2,500 using many used parts21
- Real clearance above the official figure: 50C tyre measuring 52 mm leaves about 5 mm per side, and 52–54 mm should fit in 1x2
- Aero features rare on gravel bikes: aero seatpost, S5-like seat tube, deep head tube2
- UDH, T47 bottom bracket and downtube storage2
- Steep 74° seat tube suits a racing position; geometry close to the LCR018-D with more tyre room2
- Bar choice: HBR18 flared bar in 36–42 cm, HBR20 riser upgrade, or separate bar/stem from the LCR0172
- GRX shifter shape considered more comfortable than road shifters; XT rear derailleur functionally equivalent to GRX827; Ultegra brakes praised as equivalent to GRX1
- Helpful contact via WhatsApp (Jim)2
Cons
- Long and uneven lead times: about two months for some, 4–5 months quoted for size L, and a chainstay update delayed production2
- Logo-free frames no longer offered; custom decals or paint cost $250–300, custom silver decals $450 minimum2
- Official tyre limit of 45 mm with 2x is a step back from the LCG071; wide internal rims may balloon 45 mm tyres to 47–48 mm21
- Short reach and high stack: smallest size has 547 mm stack and no XS is planned; seat tube is short for tall riders2
- Proprietary aero seatpost, with concerns about its saddle clamp from the LCR0182
- Electronic shifting only; no mechanical compatibility2
- No fork mounts; only two top tube mounts2
- HBR20 riser may not be strong enough for very rough gravel, according to LightCarbon itself2
- No Black Friday or 11.11 discounts on new frames2

The post drew discussion on the unusual groupset mix, seat tube stripe direction, 2x setup tire clearance, and weight comparisons.

The LightCarbon LCG072-D (forum name LCR72) is an aero race gravel frameset with an S5-style seat tube, aero seatpost, straight 1 1/2 in head tube, T47 85.5 mm, UDH, flat mount 160/160, downtube storage and full internal routing for electronic groupsets only. It costs $719 with fork, seatpost, headset, axles, storage bag and the HBR18 integrated bar (8 mm rise, 69 mm reach, 36-42 cm); the new HBR20 30 mm riser is a $70 upgrade, though LightCarbon itself warned it may not suit very rough gravel. A claimed 1100 g size M. Officially it takes 50 mm tyres with 1x and 45 mm with 2x, but LightCarbon's own photos show a 50C tyre measuring 52 mm on a 32 mm rim with about 5 mm per side, and owners measured 62 mm between chainstay and seat tube, suggesting 52-54 mm fits. For 2x, GRX or 105 front derailleurs leave more room than Ultegra/Dura-Ace 12-speed. Geometry has short reach and high stack (547 mm on the smallest size) with no XS planned. First frames reached buyers in October 2026: orders from August arrived in about two months, while large sizes and painted frames are quoted at 50-80 days to 4-5 months. New frames now come only with LightCarbon's logo or custom decals at a $250-300 paint charge; custom silver decals carry a $450 minimum. Jim answers fastest on WhatsApp. Concerns remain about the seatpost's saddle clamp design, borrowed from the LCR018.
