What Our Gearhead(R) Experts Are Saying: "I swapped to the SILCA 3D-printed titanium hanger on my trail bike and the difference was instant-crisper shifts, no flex, and it stayed aligned after a crash. It's lighter and way stiffer than stock aluminum, and I love that it's designed to protect the frame if things go wrong. It's one of those upgrades you don't realize you need until you feel it."When it comes to precision shifting, every small part matters-and the SILCA UDH Derailleur Hanger proves it. Built from 3D-printed titanium using AI-generated internal geometry, it's up to 12 times stiffer and several grams lighter than traditional aluminum hangers. The result? Faster, more accurate shifts that stay consistent ride after ride, even under the torque of today's electronic drivetrains. This hanger delivers elite performance with real-world durability. Its intelligent fracture notch ensures the hanger-not your carbon frame-takes the hit in a crash, while its natural stiffness keeps your drivetrain perfectly aligned. Whether tackling rough singletrack or racing through crit corners, this upgrade keeps your shifting sharp and your bike safe.
