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. Maximum tire clearance is 50mm (700c) or 2.0" (650b), which some find limiting. 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.

AI Summary

Pros

  • Affordable price for a carbon aero gravel frameset ($719 including many components).
  • Lightweight at 1100g for size M (claimed).
  • Includes downtube storage and integrated cockpit (HBR18 flared bar).
  • Good tire clearance up to 50C (700c) or 2.0" (650b).
  • Steep seat tube angle (74° effective) preferred by some for racing position.
  • UDH hanger for easy derailleur compatibility.
  • HBR18 handlebar now available in 36cm width for narrower shoulders.
  • LCR73 variant offers similar frame without wind-eye for cleaner look.

Cons

  • Short reach geometry may not fit taller riders or those with long arms; sizes run small.
  • Seatpost is a proprietary aero shape (not 27.2mm), limiting comfort options.
  • Long production lead time (4-6 months).
  • Some users desire longer reach and more fork rake for better handling.
  • Uncertainty about clearance for wider tires (e.g., 2.1" Thunder Burt) with wider rims.
  • Max tire clearance is 50mm, which some find disappointing.
  • Initial HBR18 bar width only available from 38cm; 36cm option later confirmed.
  • Frame sizes may be too small for very tall riders (e.g., XL ~53.6cm top tube).
