TanTan TT-R18

A user in r/ChineseCarbon shared their experience building and riding the TanTan TT-R18 (also referred to as Seraph TT-R18), a Chinese carbon road bike. They purchased it as a complete set for €1300, including shipping and customs to Germany, and found it comparable to bikes costing over €3500. The bike was praised for its value, ease of assembly, and performance, though some minor build quality aspects were noted. Comments highlighted its unbeatable price-to-performance ratio, but also mentioned it's not UCI-approved for competitive racing.

The TanTan TT-R18 is a disc brake road frameset marketed as super light with T1000 carbon, though several forum users dispute that claim. It features a T47 bottom bracket, Universal Derailleur Hanger (UDH), full internal cable routing, and 32mm tire clearance (with 35mm reportedly fitting). The frame weight is approximately 1052g in size S, which many consider heavy for a 'super light' frame. The geometry is aggressive with a low stack, which may appeal to some riders. Users praise the overall looks and build quality of the delivered bike, and it offers great value for money, especially the full build with Shimano 105 at $899. However, concerns include poor customer service, frequent release of new models, and the frame being assembled from existing molds. Also, the material spec is questionable. Overall, it's an interesting budget option for those comfortable with the risks.
