Specialized frames with 1x drivetrains don't have front derailleur mounts from the factory, which makes sense until you decide you'd rather have a 2x setup for longer days or hillier terrain. The Specialized Front Derailleur Mount Kit adds braze-on front derailleur compatibility to Specialized frames designed around single-ring drivetrains, giving you the option to run a traditional double crankset without hunting for a different frame.

The mount attaches to existing frame bosses that Specialized includes on their 1x-specific frames—they're tucked away and easy to miss, but they're there precisely for this kind of conversion. Installation is straightforward with basic tools, and once mounted, the braze-on interface accepts any standard braze-on front derailleur. This means you can pair it with whatever groupset you're running, whether that's Shimano, SRAM, or Campagnolo mechanical systems.

One thing worth noting: this kit works specifically with Specialized frames that have the hidden mounting bosses. Not every frame in the lineup includes them, so you'll want to check your specific model before ordering. The bosses are typically located on the seat tube where a front derailleur would normally sit—if you see two small threaded holes, you're good to go. If your frame is truly 1x-only without provisions for this mount, you'd need to look at clamp-on front derailleur options instead.... Read More
