Reviews & Ratings
The TanTan TT912 is a UCI-certified carbon fiber time trial/triathlon frame, described as a 2019/2020 disc-brake revision of an older rim-brake design with modern fat-tube aesthetics.

Key attributes include: price varies based on configuration (custom paint jobs cost extra, e.g., USD 280), frame weight around 1.6 kg (with accessories), total build weight approximately 10.3 kg with mechanical components, material is carbon fiber, standards include BB386-24 bottom bracket, SRAM UDH-style derailleur hanger, and clearance for up to 32 mm tires. It features storage options like a top-tube bento box mount and internal triangle storage, but quality control issues are common.
