Imagine revolutionizing the world of cycling with cutting-edge 3D-printed titanium that pushes the boundaries of speed and customization— that's exactly what Britain's J.Laverack is doing with their latest road bike launches. Get ready to dive into how these innovations could change the game for serious riders everywhere.
J.Laverack, the innovative brand hailing from Rutland, is set to showcase two groundbreaking bicycles at this week's Rouleur Live cycle show in London (https://www.rouleur.cc/pages/rouleur-live). These aren't just any bikes; they're pioneering uses of 3D-printed titanium technology. The AM64 Carbon cleverly merges 3D-printed titanium elements with a complete carbon fiber seat tube, slashing weight while boosting the bike's flexibility for a smoother ride. On the other hand, the Speedform is being hailed by the company as 'the future of titanium aerodynamics,' promising a sleek, wind-cheating design that's tailor-made for performance. And this is the part most people miss: how these bikes blend high-tech manufacturing with personalized fit, potentially making off-the-shelf carbon frames feel outdated.

Let's kick things off with the AM64 Carbon, which is hitting the market immediately and exciting riders who want top-tier performance without waiting. This model builds on the established AM64 series (https://www.jlaverack.co.uk/am64/), seamlessly combining the exacting accuracy of 3D-printed titanium with the responsive snap of carbon fiber, as J.Laverack proudly explains. For those new to bike tech, 3D printing—also known as additive manufacturing—allows for intricate designs that traditional methods can't match, layer by layer building the parts like a high-tech sculptor.
Breaking down the name: 'AM' refers to additive manufacturing, or 3D printing, and '64' nods to the Ti 6-4 alloy, a durable titanium blend called 6Al-4V that's popular in aerospace for its strength-to-weight ratio. The AM64 lineup represents J.Laverack's premium offerings, featuring 3D-printed components alongside double-butted titanium tubes (thinner in the middle for lightness without sacrificing strength) and fully concealed cable routing to keep things clean and aero. This advanced approach draws directly from their collaboration with Aston Martin (https://www.jlaverack.co.uk/gallery/j-laverack-x-aston-martin-1r-xenon-grey/), where similar tech crafts ultra-exclusive frames, and now it's accessible to more cyclists.

The real innovation in the AM64 Carbon lies in its full-carbon seat tube paired with an integrated seatpost, a fresh twist that elevates the design. As J.Laverack co-founder David Clow describes it, 'We use 3D-printed titanium connectors linked to titanium tubes, but the seat tube itself is carbon fiber, stretching from the bottom bracket area up through the junction of the seatstays and top tube, capped with a 3D-printed titanium top piece for the seat mast.' This setup isn't just eye-catching—think of it as a stylish fusion that reduces overall weight and enhances the bike's ability to absorb road vibrations, making long rides more comfortable.

David Clow adds that this multi-material approach, proven in the Aston Martin bikes, not only turns heads with its aesthetics but also trims grams off the frame while improving ride compliance. True to J.Laverack's ethos, every bike offers fully custom geometry, meaning it's molded to your body's unique measurements for optimal comfort and efficiency. 'Our AM64 Carbon is all about merging 3D printing with carbon composites in ways we've never done before,' the brand notes. 'It's engineered for blistering speed, yet personalized just for you.' For beginners, compliance here means the frame flexes just enough to soak up bumps, reducing fatigue on rough roads.

The carbon seat tube is securely bonded using an ultra-tough adhesive—often called the 'strongest link' in the chain. 'We've relied on this bonding technique for the Aston Martin project, and it's thrilling to bring those insights to our road bikes,' Clow shares. This trickle-down tech democratizes luxury-level engineering.

Buyers have options: a standard straight head tube or a premium 3D-printed version that adds £500 to the cost for enhanced aerodynamics. Like its siblings in the AM64 family, it includes internal cable management and exquisite laser engravings for that bespoke touch.
You can snag the AM64 Carbon as a frameset, complete with an ENVE carbon fork, handlebar, stem, headset, and ÆRA No.1 BSA bottom bracket, starting at £6,995. For a full build—featuring ÆRA carbon wheels and a Shimano 12-speed Ultegra or GRX Di2 groupset—prices begin at £9,745. The initial 50 framesets and builds will be limited-edition numbered pieces, and you can opt for custom paint jobs and graphics to make it truly yours. Plus, J.Laverack is sweetening the deal with a complimentary bike fit and custom geometry service (normally £500) on new orders. It comes in variants like R J.ACK, J.ACK, GRiT, Pilot, and Contour.

We haven't had the chance to see the AM64 Carbon up close yet, but it'll be on display at Rouleur Live. From the photos, it's clear this bike is a stunner, blending form and function effortlessly. But here's where it gets controversial: is mixing titanium and carbon the ultimate upgrade, or does it complicate maintenance for everyday riders? We'll touch on that more later.
"The future of titanium aerodynamics"
Shifting gears to J.Laverack's other star, the Speedform, which the brand touts as 'the world's most personalized, entirely 3D-printed, aero-optimized, and CFD-tested titanium road bike.' That's a lot to unpack—CFD stands for computational fluid dynamics, a computer simulation that predicts how air flows over the bike to minimize drag, much like virtual wind tunnel testing without the actual wind.

After 20 months of development, inspired by a 2017 track bike project, the Speedform ditches conventional round tubes for a fluid, sculpted shape. It consists of three meticulously 3D-printed titanium sections welded together flawlessly: the rear triangle as one piece, the seat and top tube intersection as another, and the forward part of the front triangle as the third. This modular design allows for shapes that slice through the air more efficiently than traditional frames.

Key aero features include dropped seatstays to cut wind resistance at the rear, a 3D-printed seatpost, and an optional integrated stem for a seamless cockpit. Cables route internally for cleanliness, the bottom bracket is the threaded T47 standard (great for durability and ease of service), and it's tuned for 30mm tires but can handle up to 32mm—ideal for modern road setups balancing speed and comfort.

Diving deeper into the CFD story: Partnering with Loughborough University, J.Laverack ran sophisticated simulations. The results? Compared to their R J.ACK Disc model (check our review here: https://road.cc/content/review/jlaverack-r-jack-disc-classic-312945), the Speedform cuts aerodynamic drag by 20-26% at speeds from 30-48 km/h (about 18.6-29.8 mph). For context, that's like saving precious seconds in a race without pedaling harder.

Professor A. Duncan Walker, Chair in Applied Aerodynamics at Loughborough, chimes in: 'The CFD work shows this new aero frame delivers major drag savings over standard round-tube bikes. At real-world cycling speeds, that's 20-26% less resistance, translating to up to 17 watts saved—remarkable results from smart shaping and 3D printing prowess.'
But let's introduce a subtle counterpoint: J.Laverack only compares to their own all-rounder R J.ACK Disc, not dedicated aero rivals from other brands. Does this make the claims feel a tad selective? It's a fair question that sparks debate in the cycling community—after all, true innovation should stand up against the competition.
Each Speedform frame is crafted to the exact millimeter via parametric design software, which adjusts every angle based on your body scan and riding style. This level of customization is a game-changer, something mass-produced carbon bikes simply can't replicate. Imagine getting an aero-optimized frame that fits like a glove, no compromises.

Like the AM64 Carbon, the Speedform prototype will appear at Rouleur Live, but it's not ready for prime time. This rideable test mule still needs rigorous testing, plus a weight-reduction phase to shed excess grams—current build weighs 8.6kg, but refinements will lighten it further. Production is slated for mid-2025 in limited quantities, with pricing TBD.

'We're thrilled with the progress and want real-world feedback early,' says David Clow. One standout aspect? Offering bespoke geometry for aero positions—start with a wind-tunnel-minded bike fit, then build the frame around it. With 3D printing, they can reinforce critical areas like the down tube for stiffness while trimming material elsewhere, maintaining strength without bulk. For example, internal lattices could add rigidity where needed, a trick traditional welding can't pull off.
