The GeoMetron G1 isn’t just a bike — it’s a tool for going further, pushing harder, and riding with purpose. From sunrise ridgelines to cloud-chasing descents, it’s built to carry you into terrain that challenges both rider and machine.

With comfortable, consistent suspension, interchangeable wheel sizes, adjustable geometry, and long travel, the G1 is built for total confidence on the steepest lines. Designed to evolve with you — not expire.

To find the right setup for you, get in touch — we’ll start by understanding your riding style, terrain, and goals, then tailor the frame spec to match. Everything from geometry to suspension tune, right down to the valve caps, is built around you.

The new G1 has been in the hands of David Golay over for a comprehensive deep dive into the breadth of configuration options the G1 chassis offers.

Follow the link in our bio to find out how the bike rides in its various guises from a shorter travel trail bike to a Long travel dual crown equipped trail bike. David also shares how the new G1 platform compares to his experience with the previous generation.

Both the praise and the constructive points—mean a lot to us. It’s always rewarding to see the bike in the hands of riders who push its limits and articulate the experience so well.

Our goal is to make bikes that last longer and are easier to live with and the Nicolai/Geometron G1 GPIadds its own advances in durability, long-term reliability, and minimal maintenance.

The integration of a PINION gearbox offers significant advantages over traditional derailleur-based systems. With an overall gear range of 600% and consistent 17.7% gear steps, the PINION C1.12i outperforms conventional 12-speed derailleur systems, which typically offer only 500–520% range. All moving components are sealed inside a robust, protective housing, shielding them from dirt, debris, and impact damage. The PINION C-line gearbox service interval is a whopping 10000Km. Say goodbye to bent derailleur hangers and constant adjustments, instead, enjoy precise, instant gear shifts, even under load or while stationary. Alongside these attributes the gearbox brings other performance improvements. A drivetrain unit integrated in the center of the mainframe means an optimised weight balance of the bike. The gearbox enables us to have a real impact on changing the sprung to unsprung mass ratio on a bicycle. The lighter the unsprung mass, the more reactive the suspension system and the easier it is for the rear wheel to follow the terrain. The unsprung mass consists of the components that aren’t supported by the suspension e.g. wheels, derailleur, chain and seat stays. We have been great proponents of increasing the sprung to unsprung weight ratio of our bikes, you only need to strap weights to the frame of your current bike or simply ride an Ebike to experience the effect a change in that ratio has to the ride and suspension feel.

After extensive testing with both the Medium and Small GeoMetron G1, Gundars dived deep into the geometry to identify the ideal balance, he even brought his own wheelset and tyres down to ensure a consistent ride feel between bikes. The result? Gundars went the extra mile to fine-tune his perfect fit with a tailor made G1 frameset. A custom-sized G1 with a Medium seat tube height inc. integrated seat clamp gusset and head tube length, paired with a 461mm reach—a fusion that meets his exacting demands. Every rider has unique requirements, and Gundars’ geometry was carefully crafted to meet his. His bespoke order has been submitted to , ensuring precision craftsmanship and attention to detail. Including the tailored mainframe fit, his G1 will still retain all of the Mutator adjustment range, allowing for experimentation with rear wheel size, chainstay length, and BB/head angle adjustments.

🔧⚙️Next week his new frame lands at GeoMetron HQ for the final assembly.

A Geometron G1 isn’t just a bike; it’s a tool forged for the extremes. It thrives where the landscape doesn’t compromise — where nature demands strength and endurance. The European Alps, with their towering peaks and unforgiving terrain, offer a true test of both man and machine.

Here’s carving his way down the brutal La Grave in the French Alps, showing what it means to push boundaries on the G1. A ride that’s as relentless as the mountain itself.

The cherry on the top of the G1 chassis is the bespoke damper developed in collaboration with to deliver a hand-made in Italy V4 Storia G1 🤌🏼 The V4 unit has received a number of upgrades.

Following their implementation in the first G1 Storia V3, the V4 now features spherical eyelet bearings in both eyelets, reducing stress on the shock during high load moments, improving eyelet bearing performance and longevity. This results in smoother, more sensitive suspension movement and less maintenance compared to conventional DU & Pin eyelet hardware.

A new addition to the Storia V4 is position-sensitive rebound, with a secondary piston providing a hydraulic top-out stop. This replaces the internal coil negative spring in the V3 Storia.

As with previous models, the Storia V4 allows adjustments to high and low-speed compression, rebound, and now includes adjustment of the hydraulic bottom-out circuit. Plus, true to the Storia range, it’s equipped with the LOK lever for precise tuning.

EXT is now offering an extended 5-year warranty on the Storia V4. This warranty covers the damper for up to five years from the purchase date, giving you peace of mind and long-lasting performance. To activate the warranty, customers simply need to register their damper on EXT’s website within 30 days of purchase. The program ensures that your damper remains in top condition with expert support and service.

Finally, our G1 Storia V4 dampers are available in three sizes: The standard Enduro spec 230x65mm 162/175mm RWT, the XC/trail spec 210x55mm 140/152mm, and the long travel DH spec 250x75mm 185/200mm . So if you want to take your G1 down to 140mm or up to 200mm RWT you can equip it with the G1 Storia V4 🙌🏼.

Alexander’s custom powder-coated GeoMetron G1 in size XXL arrived with him just in time for the festive break, and he wasted no time getting it built up. With the stunning mountains of Colorado as his backdrop, he headed straight to his local trails, where the bike settled into the remote singletrack with ease.

There's no way of hiding it, at 200cm tall Alexander's bike is BIG 535mm reach and 480mm Chain stays, he's rolling on 29" wheels front and rear with 170mm travel. After over a decade of riding that now fits him correctly.

We're looking forward to seeing where Alexander and his G1 end up this year with new bike stoke pulling him through the winter miles his riding is sure to reach new heights ⛰️

At GeoMetron, we’re all about pulling in the serious bike tinkerers. We draw in many riders who want to dial in their bike's geometry, tweak every little detail, and get it dialed for their exact needs. That’s why we’re stoked to have the G1, which gives you insane flexibility to adapt your setup. Here’s a solid example of a client who proudly wears the badge of top-tier tinkerer.

Check out this G1, custom built to perfection via our tailor made frame process where you can choose specific changes to your bikes tubes and geometry. It's a size Medium base with custom tweaks to the head tube and seat tube length. Plus, it still keeps the full GeoMetron mutator range, so if they want to dial in the geometry even further they have adjustable components at the chain stay and seat stay to make a multitude of incremental changes.

Yep that right, custom frames are back on the menu with the 2025 G1 frame set. Upcharge of £520.83 plus VAT. For all Tailor Made Frame enquiries email us directly on [email protected] and we'll make it happen 🪄
