15mm Axle Adapter for Marzocchi Bomber DH58 Built for Real Performance
Looking for a 15mm axle adapter for the Marzocchi Bomber DH58 that doesn’t flex, loosen, or fail?
The Feral40 15mm Adapter is a fully engineered performance upgrade, designed for riders who demand strength, precision, and reliability in downhill and enduro conditions.
This kit allows you to install a 15×110 mm Boost front wheel into a 20×110 mm Marzocchi Bomber DH58 fork using a solid 15 mm thru-axle, not a hollow tube or sleeve system.
Solid Axle Design – Why It Matters
The Feral40 uses a single-piece solid axle, CNC-machined from 7075 aircraft-grade aluminum & 1 fork adapter.
The result:
-
Increased torsional stiffness
-
More precise steering
-
Improved braking control
-
Long-term durability under extreme loads
Precision CNC Machining
Every component is CNC-machined with extreme precision for a perfect interface with the Marzocchi Bomber DH58 fork. The threaded adapters install smoothly and stay locked in place — no rattling, no movement.
Installation is simple:
-
Install with a standard Allen key on your park tool
-
Everything else on the fork remains unchanged
