Lifetime Warranty


The SILCA Lifetime Warranty covers products from manufacturing defects for the lifetime of the user.  It further covers the function of all hard parts for 7 years from the date of purchase.  Expected wear and tear is not covered.  Learn more about warranties.

Derailleur Hangers are also covered under a 2 year crash replacement program.  If it breaks in a crash within two years of purchase, reach out to sales@silca.cc and we will offer 30% off a replacement hanger.

    SILCA 3D printed titanium derailleur hangers bring increased strength and stiffness to this overlooked component so critical to quick and precise shifting. Modern electronic derailleurs shift so fast, and with such force, that conventional hangers made from low grade aluminum plate will flex up to 4 degrees during a shift resulting in less precise and slower shifting. Using advanced 3D modeling with AI generated structural infill, SILCA 3DP Hangers are 2-7x stiffer than aluminum hangers while also being 2-6 grams lighter depending on model.

    For Shimano Direct Mount compatibility the SILCA 3DP Direct Mount Hangers offer 8-12x higher stiffness with 4-10 gram weight savings by eliminating the use of the direct mount link from the assembly.

    Already in use at the World Tour level SILCA 3DP Hangers were utilized in 2 stage wins of the 2023 Tour de France and are credited with maintaining derailleur alignment across numerous crashes.

    SILCA 3DP Hangers are able to be aligned by hand, and are designed with an internal fracture notch which allows the hanger to fracture and bend below the point of damage for the carbon frame to eliminate the risk of frame damage under the hardest of impacts.

      This is my second hanger! I’ve installed one on my Crux and actually found the shifting smoother so I’ve installed another on my Aethos. I’ll give that a go soon.

      Poor finishing tolerances

      1 out of 5 for finishing / 5 out of 5 for performance.

      There was a pretty major issue with the particular hanger I received. The hole for the thru-axel was basically oval.

      When I first installed it it I quickly realised it was not finished to a precise standard like the OEM part. I tried two methods to install it. The first was to just screw in the mounting screw then put the thru axel in to check alignment. The thru-axel wouldn’t screw all the way, so tried a second method of installing it loose with the thru-axel fully bolted and then tighten the mounting bolt. This completely locked up the thru-axel and was unworkable. I ended up using a Dremel to file out the diameter of the thru-axel hole to fix this.

      Not an ideal experience for an expensive upgrade but understandable given it is not a mass produced piece.

      On the positive side, it seems to have greatly improved shifting performance.

      Install went great once I realized it replaced both parts of my particular dropout/hanger (Aethos). Shifting is amazing and is a nice piece. Would recommend anyone who is curious to watch Josh's Video on YT explaining the science and rational when making this.
