Marzocchi Z1 Coil Fork – Have your prayers been answered?

by 8

When the Marzocchi Z1 fork was launched back in April 2018 we applauded the return of a simple, bomber-(sorry!)-strong air sprung fork. Long time Marzocchi fans, though, still talk fondly of the coil sprung, open oil bath original forks. Well, today, their misty-eyed musings have come true in the form of the new Marzocchi Bomber Z1 Coil Fork.

The Bomber Z1 Coil. You already know if you want one.

And if you already have a Marzocchi Z1 air fork, there will be a spring upgrade kit that you can fit to it (or to a Fox Rhythm 36 for that matter…) to get that buttery spring feel. (Hopefully you’ll like what you get as it’s a one-way journey – you can’t turn it back to air once you’ve gone to spring).

Marzocchi says of it “As terrain and riding styles have gotten rowdier and rowdier, and bikes have gotten more and more capable, the need for bomber suspension that feels buttery and bottomless has never been greater. The industry has fondly embraced recent trends towards coil-sprung rear shocks yet none of the major players have stepped forth with a complete coil fork system. Up until now, that is.”

The new Bomber Z1 Coil retains the renowned and simple to dial-in Grip damper but swaps out the air spring assembly for “the most advanced coil spring system Marzocchi has ever made”.

The Bomber Z1 already has fans among those who just want to ride. Now with coils

At the heart of this new coil system is an ultra-lightweight tempered silicon-chromium steel spring (available in four spring rates to suit a wide range of riders); coupled with a ‘noise management system’ (which looks like a bit of rubber shrink-wrap around the spring to us, but is probably far more technical) for ‘near silent performance’; an integrated air assist for progression and bottom out control; and an external preload adjuster to dial in sag and firmness off the top.

A great big buttery spring for you.

Travel can easily be changed in 10mm increments from 150-180mm (depending on wheel size) via included, reconfigurable internal spacers. The fork will come in 27.5in and 29er, with the 150mm travel version being 29er only and the 180mm version being 27.5in only. Got it?

There is also still a lengthy service interval of 125 hours of riding. Ideal for those of us who want to pump tyres and ride, without having to faff around with pressures and tokens.

Let’s do more of this instead of swapping fork tokens, eh?

The 2018 Bomber Z1 air was surprisingly affordable (comparatively) coming in at under £800. This is true of the new Bomber Z1 Coil, which will sell for £779

OK, maybe it’s more technical than shrinkwrap on the spring… just.

If you have a Z1 air, then the Coil spring kit will cost you £154.95 with further coil springs costing £54.95. Your fork will still be covered by the factory warranty.

Although the new spring kit only applies to the Z1 Bomber air (and the Fox Rhythm 36) Marzocchi (and its parent company Fox Racing Shox) hasn’t ruled out making other spring forks and upgrade kits available for other forks. It’ll be interesting to see how the takeup is.

In the meantime, kits and forks should be arriving with importer/distributor Silverfish UK any week now and they expect to have them on sale by next month. See for more details.

Chipps wasn’t around for the dawn of mountain biking in the UK, but he likes to claim that he arrived in time for second breakfast (about the time he shows up for work, then…) starting in the bike trade in 1990 and becoming a full time mountain bike journalist at the start of 1994. Over the subsequent quarter century, he has seen mountain bike culture flourish and diversify and bike technology go from rigid steel frames to fully suspended carbon fibre (and sometimes back to rigid steel as well.)

His riding style is best described as ‘medium, wheels on the ground, trail riding’ though he’s been spotted doing everything from endurance downhill racing to 24 hour cross country racing. He favours mid-travel trail bikes and claims to be wheel-size, gear, brake and tyre agnostic. In fact, his garage spans most bicycle flavours, taking in steel hardtails, carbon trail bikes, even a mountain bike tandem, along with road, touring and gravel/cyclocross bikes.

While he’s happy to chat about bikes all day, his real interest is in the people and places that bikes can introduce you to and he talks as fondly about the trails he’s ridden and riders he’s met as the bikes that took him there.

    Should’ve had “Own the trail with the coil Bomber” as headline.

    “Travel can easily be changed in 10mm increments from 150-180mm (depending on wheel size) via included, reconfigurable internal spacers. The fork will come in 27.5in and 29er, with the 150mm travel version being 29er only and the 180mm version being 27.5in only. Got it?”

    Not clear – does that mean –
    27.5 configurable from 160-180
    29er configureable from 150-170

    ‘near silent performance’? Surely it isn’t a proper Bomber if it doesn’t make strange squirty/squishy noises?

    Oh yes. However, please can I have it in shorter travel flavour as well?

    Still loving my 98/99? Z2 BAM.

    Can I have a coil spring for my 140mm Float CTDs please ?

    *Adds to Chromag Doctahawk fantasy build list…
