Huge shoutout to TanTan for sending me this GR201 Gravel Frame. Is it the do-it-all frame with wide clearance for tires, storage on the downtube, and sleek looks? I'm really looking forward to building this up in the coming weeks for my commute to work on roads and trails.

Brand Day
CadreTanTan GR-201
Créé le : 5 juin 2025The reviewer presents an unboxing and initial inspection of the TanTan GR-201 carbon gravel frame. They state that TanTan sent the frame for review. The reviewer highlights its features: clearance for 50mm tires, numerous mounting points for accessories, and a down tube storage compartment, which they note is the first they've seen on a Chinese frame. They chose a 54cm size to match their road bike's geometry. The frame has a black matte carbon weave finish with a silver Seraf logo. They note the down tube looks chunky, likely for reinforcement. Internally, the frame is described as pristine and EPS molded. They discuss the included components like the seat post, handlebar, and storage bag, and detail the build process they plan to undertake. They ask viewers for feedback if they have ridden this or the similar Tideace GV20 frame.
