A custom titanium road bike that fits, so you can ride it for as long as you want to, with a spec that suits the way you ride.
Every rider asks something different of a road bike. Yours is built around what you ask of it, and made to keep *for* *years* *of* *riding.*

Every option is a trade-off on a spectrum, and the build finds your point on it.
Fit is speed. Your fastest position is the one you can hold for as long as you plan to ride. Will sets your reach, stack and steering around it.
Race and endurance are two ends of a range, and your geometry can sit anywhere along it. 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.
Room to change your mind. A frame built around 40mm still runs 32s well. On rough Australian roads, a 35 is often as quick as a 28, and more comfortable.
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 is the traditional road bike: simple, serviceable, period-correct with a horizontal top tube.
Carbon as standard, titanium for a cohesive look, extra comfort and durability.
The trade-off: a titanium fork adds a few hundred grams over carbon and will last as long as the rest of the bike. 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.
Raw brushed titanium is the classic. From there, add as much or as little as you like.
You don't need to know any of this before calling. Will can help interpret the way you ride and turn that into the most appropriate spec.
Choose your terrain, tyres, drivetrain, fork, mounts and finish, and your bike is drawn live as you go. Nothing is final, and every detail can change on the call.

James, racing his custom road build
This bike has completely changed how I ride.
“After two carbon frames let me down, I wasn't sure what to expect from titanium… It's fast, it's planted, and I'm not thinking about the frame anymore, I'm just riding.”
James wanted a sleek road bike he could “ride hard fearlessly” after two carbon frames let him down. He trains on it every chance he gets, and races it.
“The bike itself rides like an absolute DREAM and I've had so many compliments on it I've lost count. Will worked with the budget I gave him to pull together a stunning, fully-customised road weapon that went beyond what I expected.”
“It is clear Will's Peregrine is the most efficient bike I have ever ridden, including custom steel and higher-end carbon in recreational and competitive settings. It descends with exceptional balance and tracks flawlessly, as well as being responsive on climbs.”
“Incredibly supple and compliant, while also cutting through the air. It looks fantastic, and lets me chew up the kilometres in comfort and style. If you want something custom, and like titanium, I highly recommend AUREN.”
We learn how you ride, where, and for how long. 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 to five months on, you're riding it.
A free call about how and where you ride, and what you'd want in a custom bike.
"I'm two metres tall. Custom geometry was the obvious fix, but custom bikes in Australia were expensive. As an engineer, I thought I could provide the solution."
In 2018 Will met Dave, who wanted a custom titanium gravel bike. He became Auren's first customer, and now a close friend. People in their circles noticed. Five more followed. Will still designs, assembles and delivers every bike himself.
An important part of the bike being right for you is that it suits your circumstances and your budget. There is a wide variation in how we can do and spec things to suit.
A custom titanium frame built to your fit, with the fork to match. Build it up yourself, or with your local shop.
Wheels, groupsets and finishing kit can often carry over. Will tells you what transfers cleanly and what's worth upgrading.
Will specs, sources and assembles every part, then hands over a bike that's ready to ride.

Email Will →Each material is a trade-off. Carbon is the lightest and can be tuned for stiffness, but a crack usually means a new frame. Steel is comfortable and repairable but heavier. Aluminium is stiff and affordable but harsh on long rides. Titanium sits between them: light enough to be quick, compliant enough to stay comfortable, and tough enough to keep for decades with no paint or rust care. The trade-off is cost, and finding someone who builds it well.
Titanium takes the edge off high-frequency road buzz, the chatter you feel through your hands and saddle on chip seal and broken bitumen. It doesn't feel soft or slow under power. The difference shows most in the later hours of a long ride.
Yes. A top titanium frame is a few hundred grams heavier than a top carbon one, roughly 300 to 600g depending on spec. At amateur and sportive level, fit, position and tyres make a bigger difference than that gap, and riders race their Aurens. The real question is whether carbon's weight saving is worth its cost and fragility for how you ride.
Decades, short of crash damage. Titanium doesn't fatigue the way aluminium does, doesn't degrade like carbon can, and doesn't rust. The components will wear out many times over before the frame does, which changes the maths on the purchase price if you've spent years replacing bikes.
Race geometry puts you longer and lower, for aerodynamics and power on shorter, harder efforts. Endurance geometry raises the front and shortens the reach, so the position holds up over six or eight hours. The speed gap is often smaller than people expect, because an aggressive position only pays off if you can hold it for the length of your ride. Which suits you depends on how long you ride and how your body likes to sit, and that gets worked out in the fit session.
Reach and stack come first, then saddle height and setback, which matter for knee health and power. In Melbourne that's a jig-based fit session in the second or third week. Further away, a recent professional fit or the numbers off a bike you already like can be the reference. The geometry is drawn from that, so the frame is built around a position you've already tested.
Wider than the sport assumed for years. On smooth roads, 28 to 32mm is common. On rough Australian bitumen, a 35 is often as quick as a 28 and more comfortable, because a wider tyre at lower pressure rides over the surface instead of bouncing off it. Auren road frames clear up to 700×40, so you can change your mind about tyres later.
Electronic shifting is precise and consistent regardless of cable stretch or tired hands, and it manages the front derailleur for you. Mechanical gives a tactile feel and no batteries to charge. Both shift well when properly set up. The difference shows most on long, hilly days.
Wheels change how a road bike feels more than most upgrades. Deep carbon rims are quick in a straight line but catch crosswinds and cost more to replace. Shallower rims are lighter to spin up and easier to live with. Tubeless lets you run lower pressures and often seals a puncture mid-ride. Spoke counts are set for your weight and how you ride, so the wheels hold up as well as the frame.
Framesets run $3,850 to 4,600. Complete road builds usually land between $7,000 and $16,000, depending on groupset, wheels and finishing kit. The first call includes a pre-quote, so you know where your spec lands before you commit to anything.
Four to five months from the first call to your first ride. That covers the discovery conversation, the geometry session, the frame build and parts sourcing, then final assembly and delivery.
Often, yes. Wheels, groupsets and finishing kit can carry over if they're in good condition and suit the new build. Raise it on the first call and Will can tell you what transfers cleanly and what's worth upgrading.
No. Will assembles your bike in the Melbourne workshop and delivers from there. The geometry session is easiest in person, but remote fits are common, and we work with riders around the country.
The titanium frame and any Auren-made components carry a lifetime warranty against manufacturing defects, for the original owner, for as long as you own the frame. Third-party parts like SRAM, Shimano and DT Swiss are covered by their own manufacturer warranties, and we'll help with any claim.
