Custom titanium road bikes built to your geometry and your riding style. Endurance vs performance-tuned, properly fitted, and finished the way you want it.
Every option is a trade-off on a spectrum, and the build finds your point on it. Pick a topic.
Tailored to you, for maximum comfort and efficiency. Tap the dots, then flip the frame between its two characters.
Fit is speed. The fastest position is the one you can hold all day.
Most riders sit between the two poles. Custom means being placed exactly, not bucketed. Your numbers come from a bike fit (best), your current bike, or your measurements.
Anywhere from 700×32 to 700×40, depending on how and where you like to ride. On road, this is fine-tuning ride quality.
Counterintuitive but true: on real Australian roads, the 35 is usually faster than the 28.
Clearance is a frame decision, not a tyre decision. A frame built around 40mm still runs 32s perfectly. Buy the headroom once, change tyres forever.
From fully external for ease of build and servicing and a traditional look, to fully hidden for a modern stealthy look, including one-piece cockpit options.
External. The traditional road bike: honest, serviceable, period-correct with a horizontal top tube.
Carbon as standard, titanium for a cohesive look, extra comfort and durability.
The fork that matches the frame — in material, in compliance, in lifespan.
The honest trade: titanium forks are heavier than carbon. The trade is grams for decades. Fork choice is also matched to the routing decision, so a one-piece cockpit gets the right steerer and the build stays coherent.
Traditional horizontal top tube or compact frame, seatstays meeting the top tube or dropped, tube profiles and diameters tailored.
Diameters are tuned to your weight and stiffness preference as well as the look. These choices don't change who the frame fits, they change what it says.
Geometry decides how it fits. Frame style decides what it says.
Every other part and frame spec can be tailored to your ride and your budget.
You don't need to know any of this before calling. Will walks you through every decision with a recommendation and a reason.
Real riders, real builds. Here's where one Auren road bike has ended up.
We learn about you and your dream ride. You get a pre-quote and an initial spec.
A jig-based bike fit that sets reach, stack and angles around your body and the way you ride.
The titanium frame is built to spec while your chosen parts are sourced and delivered.
Will assembles, runs final checks, and delivers. Four months on, you're riding it.
No obligation, just a convo about what you'd want in a custom bike.
Road is one of several titanium builds. If you're weighing up where you ride most, start here.
From spec choices to the fine print, everything you need to understand what you're getting.
Each material makes real trade-offs. Carbon is lighter and can be engineered for specific stiffness targets, but a crack usually means replacement. Steel is compliant and repairable but heavier. Aluminium is stiff and affordable but fatiguing on long rides. Titanium occupies a position none of the others fully cover: light enough to be fast, compliant enough to be comfortable, and durable enough that a well-built frame is effectively a life purchase. It doesn't degrade, doesn't corrode, and doesn't need protecting from the elements. The trade-off is cost and the difficulty of finding someone who builds it well.
The material has natural compliance. It absorbs high-frequency vibration that aluminium transmits directly and that carbon requires careful layup to manage. On a long ride over rough tarmac or chip seal, that makes a real difference to how you feel at hour four. It's not soft in a way that loses efficiency, it's more that the buzz and chatter of the road is filtered before it reaches your hands and sit bones. Riders who switch from aluminium to titanium almost universally comment on it within the first few hours.
Yes. The UCI weight limit for road bikes is 6.8kg, and a well-built titanium road bike sits comfortably at or near that. The weight difference between a top titanium frame and a top carbon frame is real, perhaps 300 to 600g depending on spec, but at the amateur and sportive level, that gap matters far less than fit, position, and the rider. Titanium has been raced at a professional level and won. The question isn't whether it's fast enough. It's whether the weight saving of carbon is worth the cost and fragility trade-off for how you actually ride.
Race geometry prioritises aerodynamics and power transfer: longer reach, lower stack, more aggressive position. It suits riders with good flexibility and core strength who are riding hard for two to four hours. Endurance geometry raises the front end, shortens the reach, and puts you in a position sustainable over six or eight hours without back or neck strain. The difference in actual speed between the two is negligible for most riders, an aggressive position only pays off if you can hold it without deteriorating. Most custom road bike buyers, if they're honest about their riding, suit endurance geometry.
Wider than the sport has traditionally assumed. 25mm was the standard for years. 28 to 30mm is now common, and for good reason. A wider tyre at lower pressure has less rolling resistance on real-world road surfaces than a narrow tyre pumped hard, the contact patch is more compliant and the tyre deflects less. 28mm is a sensible default for most road riding. 30 to 32mm suits longer days, rougher roads, or anyone who values comfort. On a custom frame, clearance can be designed to suit rather than worked around.
Electronic has become the cleaner choice for road riding. Precise, consistent shifts regardless of cable stretch or hand fatigue, and the ability to manage the front derailleur without thinking about it. The argument against, repairability in the field, matters less on road than off-road, since you're rarely far from a shop. Mechanical is still a strong choice if you prefer tactile feel and a system with no batteries to manage. Both shift accurately when properly set up. The difference shows most on long hilly days, where cumulative hand fatigue becomes a real factor.
Wheels have a bigger effect on road bike feel than almost any other component. Deep section carbon rims are fast in a straight line and stiff in a sprint, but sensitive to crosswinds and expensive to replace after a crash. Shallower rims are lighter in rotation, more predictable in wind, and easier to live with day to day. Tubeless is worth serious consideration: lower pressures, no pinch flat risk, and a puncture that often seals itself mid-ride. For most riders doing mixed road riding and sportives, a 35 to 45mm carbon tubeless setup covers most ground well.
Road bike fit is more position-sensitive than MTB or gravel because you're in a narrower range of movement for hours at a stretch. Reach and stack are the primary numbers. Too much reach and you load your lower back and fight the bike on climbs. Too little and you're cramped, losing power, and straining your neck. Saddle height and setback matter enormously for knee health and power output. A professional bike fit before commissioning a custom build is money well spent, it reduces the chance of building a frame around the wrong position.
Effectively indefinitely under normal use. Titanium doesn't fatigue the way aluminium does under repeated load cycles, doesn't degrade over time like carbon can, and doesn't rust. Crashes can bend or crack any material, but short of impact damage, there's no structural reason a well-built titanium frame can't be ridden for 30 or 40 years. The components will wear out many times over before the frame becomes a question. For anyone who's spent years buying and replacing bikes, that longevity changes the arithmetic on the purchase price considerably.
Carbon wins on weight. A high-end carbon frame is typically 300 to 600g lighter than a comparable titanium frame, and at the very top end can be engineered more precisely for stiffness in specific areas. Titanium wins on durability, repairability, and longevity. A carbon frame that takes a knock in the wrong place may be structurally compromised without showing it. A titanium frame ridden hard for ten years is the same frame. For riders who treat a bike as a long-term tool rather than a performance item with a shelf life, that distinction matters more than the weight difference.
