If your frame uses a UDH (Universal Derailleur Hanger), SILCA's 3D-printed titanium version gives you a stiffer, lighter hanger that holds alignment through hard shifting and knocks.

Highlights

  • Fits frames built to the UDH standard
  • Shimano (Direct Mount) version replaces the B-link: 8-12x stiffer and 4-10 g lighter (SILCA figures)
  • SRAM (standard) version: 2-7x stiffer, 2-6 g lighter than aluminium (SILCA figures)
  • Each hanger verified to within 0.2 degrees of parallelism

Why titanium

Modern electronic derailleurs shift fast and hard enough to flex a conventional aluminium-plate hanger by up to 4 degrees mid-shift, costing precision and speed. SILCA designs each hanger with AI-generated structural infill and 3D prints it in titanium. SILCA 3DP hangers were used on 2 stage wins at the 2023 Tour de France and are credited with holding derailleur alignment through numerous crashes.

Alignment: read before fitting

Every SILCA hanger is verified to within 0.2 degrees of parallelism before it ships. Do not use a hanger alignment gauge or try to bend it: titanium resists cold-bending, and forcing it risks snapping the internal fracture geometry designed to protect your frame. If alignment measures out after fitting, SILCA points to the frame, a dirty dropout or a bent derailleur cage instead. Hanger fitting and gear set-up are available as a separate Tune Cycles workshop service.

Compatibility & fit

For UDH-compatible frames only. SILCA says that if your frame is not UDH-compatible and isn't on its list of frame-specific hangers, it has no confirmed fit. Direct mount hangers replace the B-link on Shimano derailleurs. For non-UDH frames, see SILCA's frame-specific Direct Mount and Standard 3DP hangers.
