Lightcarbon LCR72 "aero racing gravel"

The LightCarbon LCG072 'Aero Racing' Gravel frame is a new offering focused on aerodynamics and racing performance. It features a Toray T700+T800+M60J carbon fiber construction, with a claimed weight of 1100g for a size M (UD matte). The frame uses a straight 1 1/2'' head tube, T47 bottom bracket, UDH hanger, and flat mount disc brakes (160mm). It comes with full internal cable routing, downtube storage, and includes a frame, fork, seatpost, headset, integrated bar/stem (HBR18, now available in 36-42cm widths), and other components. The geometry is described as having a short reach and steep seat tube angle, which has generated mixed reactions. The frameset is priced at $719, with additional costs for painting (now $250-300 for most paint jobs, including matte black with decals). Maximum tire clearance is 50mm for 1x and 45mm for 2x (WAM), which some find limiting, especially compared to the older LCG071 which fit 50mm with a front derailleur. The LCG072-D variant (with wind-eye) is expected to ship in November 2026, while a similar LCR73 model without wind-eye is also available. The HBR18 handlebar can be ordered separately for $197. A new HBR20 gravel bar is available as an upgrade for $70, with a 6-degree flare and production expected by late 2026 for the 380/100 size and all sizes by January/February 2027. The frame is only compatible with electronic shifting. Fork cannot be ordered with mounting points; only top tube has 2 mounting points. Custom painting costs $250-300 for most paint jobs. No XS size planned. Production lead times are around 4-6 months, with size M estimated at 25 days for raw finish plus 20 days for painting after pre-production checks, but a recent chainstay update may add another month of delay. The frame is not a one-piece mould, but the raw UD finish is reported to look tidy. There are concerns about the seatpost's saddle rail clamp design based on issues with the same seatpost on the LC18.
