New 2026 Aero-light frame from Light Cycling

The Light Cycling Surge RF10 is a new aero road frame from Light Cycling, designed with SL9-inspired geometry. It features T800+T1100 carbon, T47 bottom bracket, UDH, 35mm tire clearance, and FSA ACR headset standard. The frame is available for pre-order at around $629 (frame only) with custom paint options. Early user reviews are generally positive, praising the fit and finish, smooth internal routing, and comfortable yet stiff ride quality. However, there have been issues with missing parts (seatpost) and seatpost slippage. The frame is manufactured by an undisclosed factory, not Longteng, and is also sold as TanTan X68.

AI Summary
