Reviews & Ratings
The LongTeng LTK266-D-SL is an open-mold, super-lightweight road bike frame with a claimed T1100/T1000/M65 carbon blend, designed for versatile riding including light gravel and road. It features a T47 bottom bracket, UDH (Universal Derailleur Hanger), and clearance for up to 35mm tires with 6mm of clearance. The frame is praised for its low weight (around 760g for the frame, 325g for the fork), modern geometry similar to race bikes like the Tarmac SL8, and high value for money. However, it has some quality control issues with components like the headset and seatpost clamp, limited size availability (initially only S/M/L, with XL/XXL planned for later), and a non-aero, minimalist design. Users report a 'delightfully boring' ride feelโresponsive and comfortable but not excitingโmaking it a solid all-rounder for the price.
