Built for the long way home.
Set to the position you can hold on your longest ride, with room for tyres up to 700×40 when the roads get rough.
Explore road →Grade 9 titanium, drawn to your body and the way you ride. Fully custom, for roughly the price of a stock bike.
A titanium bike is one you keep. Your fastest position is the one you can hold for as long as you plan to ride, so that's the position Will builds *your* *frame* *around.*
Will, founder and engineer. Two metres tall, which is how this all started.
Every aspect of the frame design and specification can be customised. Not just the size, but how it's built, what it carries and how it looks.
Raw brushed Grade 9 titanium

A titanium hardtail that takes the hits and carries the load, with a custom titanium rack if you want one.
Explore mountain →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.
Configure yours, with the new live configurator →Claudia toured Australia for three months. Mark carries a full load and still rides singletrack. James races. Other Auren riders are touring Europe. Their bikes look nothing alike.

Build it the way that suits you. Not sure which? Will works it out with you on the first call.

A custom titanium frame built to your fit. Build it up yourself, or with your local shop.

Bring the components from your current bike onto a frame built for you, and upgrade whatever's worth it along the way.

Will specs, sources and assembles every part, then hands over a bike that's ready to ride.
We're not cutting corners on the bike. We're cutting everything else.
Bikes ship from the Preston workshop in Melbourne. No racking, no distribution centre, no leases.
No showroom. You see your bike at the workshop or on your own driveway, and you don't pay High Street rent.
One engineer and a hand from friends and family. No sales team, no marketing department.
Welded by the same titanium specialist in China for eight years. Will has visited the workshop in person several times.
Every dollar we don't spend on overhead, you get back in the build.

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.

Your titanium frame is built to spec while your chosen parts are sourced and delivered. We keep you updated at every stage.

Will assembles, runs final checks, and delivers. Four to five months on, you're riding it.
Tube gauge chosen for your weight with a load on, a threaded bottom bracket, and spoke counts set for how you ride. Parts any good shop can service, and no paint to look after. Drag to look around.










"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.
Eight quick questions about how you ride. Your build sheet fills in as you go, and Will reads it before your free consult. Prefer to see it drawn? Design it in the configurator.
Still have a question? Will answers everything personally.
Email Will →Four to five months from first call to first ride. The geometry and parts selection can happen quickly. Most of the timeline is the frame build itself, with components sourced in parallel. We keep you updated at every stage.
Our complete bikes typically sit in the $7,000–16,000 range, roughly half what a comparable locally welded custom costs. Where yours lands depends on the drivetrain, wheels and finishing kit. You get a pre-quote on the first call, before you commit to anything.
No. The first call is for working that out. Will goes through every decision with you (geometry, frame type, drivetrain, brakes, cable routing, dropouts, finish), lays out the trade-offs, and you choose. You don't need to know the difference between T47 and BSA. Most riders leave with a clear picture of what they want and what it costs.
Depends what you care about. If your only priority is the lowest possible weight on smooth roads, carbon has an edge. If you also care about durability, repairability, comfort on rough surfaces and a frame you don't have to baby, titanium is worth considering. Carbon can be damaged by an impact without showing it, and titanium is far more forgiving of knocks.
Decades, ridden hard and maintained properly. Titanium doesn't rust, doesn't fatigue the way aluminium does, and doesn't degrade from UV or impact the way carbon can. We engineer ours around the industry's common failure points (headsets, bottom brackets, dropouts) and back the frame with a lifetime warranty.
We ship and consult Australia-wide. The discovery call is over the phone, and the geometry can come from a professional bike fit done near you, or from your current bike. We work it out together.
None. The consultation is free, there's no deposit to have the conversation, and you leave with a pre-quote and a clear picture of the build. If it's right for you, you go ahead. If it's not, you don't.
Every part of the frame is designed around you, not picked from a size chart. It starts with geometry: reach, stack, angles and standover drawn to your body and the way you ride, not a small, medium or large.
The rest of the frame is tailored too: tubing chosen for your size and riding, tyre clearance, dropouts and axle standards, the drivetrain it's built around (derailleur, Pinion, Rohloff or belt), cable routing, mounts for bottles, bags and racks, the finish, and any engraving. Then every component is chosen with you, so the whole bike fits your body and your riding, not an average of everyone's.

No. Fit is step two of the process, after the first call. In Melbourne that's a jig-based geometry session. If you're further away, a professional fit done near you or the measurements of a bike you already like can be the reference. Will takes it from there.
Disc road, all-road, gravel, adventure, touring, XC and trail hardtails. Everything from a clean road bike to something built for proper off-road country. If you ride it on two wheels, we can likely build it.
Off-the-shelf titanium sits in the same price tier as Auren and usually comes in two or three sizes. We build the frame around your body, your posture and the way you actually ride, so you get fully custom for the price of a stock bike.
Will designs every frame and sets the geometry in Melbourne. The frames are welded by our titanium frame partner in China, a partnership of eight years with several visits in person, which is a big part of how we keep custom affordable. Will then assembles, checks and delivers every bike himself.
Yes. Ride feel comes down to tube choice, and we spec tubing gauge around your size, your riding and the build type, not just a number on a scale. Riders race their Aurens. You get the efficiency without the harshness, because titanium takes the edge off road buzz at the material level.
Typically 1.5–2kg depending on size and geometry. You can go lighter with thinner tubing, but the bike gets stiffer, more demanding and less forgiving. The few hundred grams aren't worth the ride quality you'd lose.
As much as your riding calls for, because the frame is drawn around it. We've built bikes with 2.6" tyres on both 27.5" and 29" wheels for remote touring and loaded bikepacking, and tight, fast clearances for road. Tell Will what you want to run and he'll design the rear end and fork around it.
Yes. We're Australia's number one Pinion builder, and we build for Rohloff and belt drives too, with the right dropouts for each (split chainstay for belts, horizontal dropouts for Rohloff). Mention it on the first call and the frame is designed around the drivetrain.
Yes. Fully internal tube-in-tube routing (no rattle, no exposed housing), hidden internal, or external. The right choice depends on your build and how much you value looks against easy servicing, and Will walks you through it.
Yes. Raw brushed titanium is what most riders choose, but paint, powder coat and anodising are all options. You can also have a name, coordinates or an emblem sandblasted or engraved straight into the titanium, permanent without paint.
No. Titanium doesn't corrode under normal riding conditions: salt air, rain, sweat, mud. The raw brushed finish isn't a coating. It's the material itself, and it needs no protection to stay that way.
Yes. A frame swap is a smart way to upgrade. We build a custom titanium frame to your fit and move your existing components across, upgrading anything that's worth it while we're there. Once you sell the old frame, the net cost is often lower than you'd expect.
The frame and any Auren-made components (stems, handlebars, seatposts) are covered against manufacturing defects for as long as the original owner has the bike. If something fails that shouldn't have, we fix it, parts and labour included. Crash damage isn't covered, and the warranty doesn't transfer on resale. Other components carry their manufacturer's warranty, and we'll help you with those claims.
Very little. No paint to touch up, no coating to preserve, no rust prevention. A mild cleaner handles most things, and light scuffs buff out with a fine abrasive pad worked along the existing brushing. The drivetrain, brakes and wheels need the same care as any good bike, less again with Pinion, Rohloff or belt drive.
Will services bikes from the Melbourne workshop. Outside Melbourne, any competent local bike shop can look after it, since nothing about a titanium frame needs specialist tools. Will is happy to advise on what needs attention and when.
It's more involved than buying off the shelf, but not complicated. Will takes you through each decision in order and lays out the trade-offs each time. Most riders find it straightforward, and the build sheet above is a good way to start.
