New Tantan Seraph X71 - Replica Factor Ostro VAM V2 (UDH)

The TanTan TT-X71 is a replica of the Factor Ostro VAM V2, offered as a frameset or complete bike. Priced around $499 for the frame, fork, seatpost, handlebar, and spacer (matte black), it weighs approximately 1135g (unpainted size 56) to 1140g (painted size 58). It uses T47A bottom bracket, UDH derailleur hanger, and only supports electronic shifting. Tire clearance is tight; 32c tires fit with about 3-4mm gap. The frame is carbon fiber with EPS molding. User experiences are mixed: many praise the value and appearance, but several report quality issues like flimsy handlebars, poor brake mount alignment, seat tube blockage, and communication problems with the seller.
