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 internal 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, typically costing $800-$950 delivered. Users report a 'delightfully boring' ride feel—responsive, comfortable, and stable, with reliable mechanical performance and no issues like seatpost slippage or creaking in long-term use for some. However, recent reports indicate the stock seatpost clamp may not hold the saddle securely even at the specified 12Nm torque, requiring aftermarket replacements like the Ritchey WCS-1. Other quality control issues include poor-fitting components like the headset, limited size availability (initially only S/M/L, with XL/XXL planned for later), a non-aero, minimalist design, and thin paint prone to scratching. The ordering process can involve communication delays, but recent shipments have been progressing. For disc brakes, the front uses a 160mm rotor, with 140mm possible by flipping the adapter. Overall, it's a solid all-rounder for the price, offering an easy assembly experience for first-time builders, though attention to component upgrades may be needed.
