A custom titanium gravel or bikepacking bike that fits, so it stays comfortable for as long as you're out there, with a spec that suits where you ride and what you carry.
Gravel riders take their bikes to very different places. Yours is built for where you go, and made to keep *for* *years* *of* *getting* *there.*
From fast gravel to three months across Australia and tours through Europe. There's no house style, because no two riders asked for the same bike. Tap any photo to look closer.

There are many design choices in a custom gravel bike. Most aren't right or wrong, they're an optimisation, and a reflection of what you value most.
Built for the loaded case. Twelve kilos of bags changes how a bike steers. Will sets your geometry around the load you'll carry, so the bike stays steady and the position still feels right a few days in.
Your numbers come from a bike fit (best), your current bike, or your measurements.
From 700×40 to 27.5/29×2.6. The frame is built around the rubber your riding wants.
Two bikes in one frame. Generous clearance means the same bike runs 700c for speed and 650b with fat rubber for adventure. On rough ground, the bigger tyre is often the quicker one.
SRAM or Shimano, mechanical or electronic, 1× or 2×. Or a Pinion gearbox: sealed at the centre of the bike, with nothing hanging off the back to bend or wear out on a remote track.
Auren is Australia's number one Pinion builder, and the frame is designed around whichever you choose.
Fork choice affects speed, comfort, durability and terrain capability.
Match the mounts to your adventure. You get the mounts your riding needs, and a clean frame everywhere else.
And because the geometry is yours, a custom frame bag fills the entire main triangle, no wasted litres.
Three ways to run the cables through the same frame, from easiest to fix on a fire trail, to the cleanest possible lines.
External is fixable on a remote fire trail with what's in your pack.
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.

Kirsten and her long-range touring build
I have finally found my forever bike.
“A custom built titanium frame with Pinion gearing and electronic shifters. Will spent time, answered questions and listened to my needs and delivered in every way. I have been cycle touring for over 40 years and been loyal to 3 bikes in that time, but this is the bike that feels the most comfortable and intuitive (and looks very cool as well!).”
Kirsten came to us looking for a forever bike, something dependable enough for long, remote touring with the gears sealed away from the weather. We built her a titanium frame around a Pinion gearbox and belt drive, set up for the distances she had in mind.
“After deciding a titanium gravel bike was my next long-term purchase, I came across AUREN and pressed inquire. The next day William called… The bike fit session was a real highlight. The end result is a beautiful custom fit titanium bike that is a true pleasure to ride.”
“Having just taken delivery of my Swift Gravel bike I can't rave about it enough… It's fast, comfortable, stable, a pleasure to ride and it's beautiful. The whole experience from design to fulfilment has been a pleasure. (Oh yes, and excellent value for money.)”
“Great experience with William's input and a few stellar suggestions like the curved top tube. Exactly what I wanted, between a trail bike that can rail and an all-day, multi-day. The small touches in the frame finish and a beautifully crafted bike.”
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.
Will, founder and engineerAn 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.

For a bike you'll load up and take somewhere remote, that combination of durability and comfort is hard to beat. It also looks the same in ten years as it does on day one.
No. Most people come in with a sense of where they ride and what they're chasing, not a parts list. Will goes through every decision with you, from geometry to bottom bracket, lays out the trade-offs, and you choose. You leave the conversation knowing more than when you started.
It's a sealed gearbox at the centre of the bike that replaces the derailleur. All the moving parts sit inside, protected from mud, grit and water, so there's nothing hanging off the back to bend or wear out on a remote track. Paired with a belt drive, it's about as low-maintenance as a drivetrain gets, which is why it suits long, unsupported trips.
To a point, yes. Generous tyre clearance means one frame can run fast 700c rubber for quick days and fat 650b tyres for rougher, loaded riding. Geometry is the trade-off worth talking through: a frame tuned for the loaded case stays calm under bags where a race frame gets nervous. Will helps you find the point on that spectrum that matches how you actually ride.
From a jig-based bike fit in the second step of the process, which sets your reach, stack and angles around your body and your riding style. If you can't get to the workshop, we can work from a recent professional fit or careful measurements off your current bike.
Often, yes. Wheels, groupsets and finishing kit can frequently carry over if they're in good condition and suit the new build. It's worth raising on the first call so Will can tell you what transfers cleanly and what's worth upgrading while you're at it.
Yes. Names, coordinates, or a meaningful emblem can be sandblasted or engraved directly into the titanium, permanent without paint. Finishes run from raw brushed through to fully painted in any colour. Bring the idea to the first call and we'll work out how to do it.
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. Titanium framebuilding and quality parts both take time, and the result is meant to last decades.
It depends on the build. Geometry, drivetrain, wheels and finishing all move the final number. The first call includes a pre-quote based on what you're after, so you'll know roughly where your spec lands before committing to anything. Will is upfront about cost at every step.
None. The consultation is free, there's no deposit to have the conversation, and you leave with a quote and a clear picture of what the build involves. If it's right for you, you proceed. If it's not, you don't.
It's more involved than buying off the shelf, but it isn't complicated. Will runs through each decision in order and lays out the trade-offs, so you're never guessing. Most riders find it straightforward once they're in it.
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 Pinion, SRAM and DT Swiss are covered by their own manufacturer warranties, and we'll help you navigate any claim.
The frame itself needs almost none, no rust prevention, no repainting, no coating. The drivetrain, brakes and wheels need the same care as any quality bike, and a Pinion-and-belt build keeps even that to a minimum. Outside Melbourne, the bike services at any competent bike shop, since nothing about it is proprietary.
