Marzocchi's Bomber DJ is built from the same chassis as their flagship enduro/freeride fork, the Z1. This gives the Bomber DJ stiff 36mm stanchions, beefy chassis and the GRIP damper. This translates to a stiff and supportive ride whether you're on dirt jumps or a pump track. Since dirt jumpers are usually flung through the air and are often involved with landing separately from the rider in a crash, the burly chassis are built to withstand abuse on hard landings with or without the rider. From riding this on the street and on the pump track, I can tell you that it feels like it's going to handle abuse for years to come. This fork utilizes an air spring to make the fork lightweight and have adjustable bottom-out control. It's extremely easy to set up, and a true "set and forget" fork.
I'm very happy that Marzocchi carried over the 36mm chassis from the Z1 rather than the 34mm chassis from the Z2, as I prefer the fork to feel super stiff on dirt jumpers. This gives me more confidence that I can push myself to jump a bit higher and push a bit harder on the pump track. I fear the 34mm chassis would have left a bit to be desired, but the 36mm chassis feel amazing. Plus, the GRIP damper we've known to love is not only extremely reliable, but just offers incredible performance. With just 100mm of travel, being able to absorb small bumps is important, and the GRIP damper does that exceptionally well.
