TanTan / Seraph new frame... GR047

The TanTan GR047 is a Chinese gravel frameset featuring a T47 threaded bottom bracket, which is praised for easier serviceability compared to press-fit. The frame geometry appears similar to the Wilier Jena. Weights are approximately 1.25 kg for the frame and 450 g for the fork. The frame uses a T47 BB, which is a rarity among Chinese frames. Some users reported minor quality issues such as epoxy in threads, buried brake inserts, and rough headset cups. The included seatpost (zero offset, single bolt) was criticized for slipping. Overall, the frame is considered a good value but may require some cleanup and careful assembly.
