Have a question before you buy?
The frame is built around a dedicated Pinion shell sized to your specific gearbox model, rather than a standard threaded or pressfit BB. Tell us which Pinion gearbox you're running (or planning to run) and we build the shell to match.
A sealed gearbox at the bottom bracket means no derailleur to bend or knock out of alignment, consistent shifting regardless of chain line, and a gear range that a derailleur setup often can't match — appealing for touring, bikepacking, and rough-terrain riding where reliability matters more than marginal weight savings.
Pinion gearboxes are commonly paired with a belt drive instead of a chain — cleaner, near-maintenance-free, and we've built for Australia's leading Pinion build list including belt-compatible dropouts. Tell us if you're planning a belt drive and we'll confirm dropout spacing to suit.
This is a made-to-order frame — tell us your specific Pinion gearbox model and intended riding, or reach out to Will and we’ll confirm the full spec before the build starts.
Tools needed: None for you — this is a frame, not a bolt-on part, so "installation" is really the build process.
Geometry and gearbox confirmation. We lock in your geometry, and confirm your specific Pinion gearbox model so the shell is built to match.
Spec confirmation. Tyre clearance, dropout standard (including belt-drive compatibility if wanted), brake mount, seatpost diameter, and mounts are confirmed against your intended riding.
Build. Your frame is welded by our titanium frame partner to the confirmed geometry, Pinion shell, and spec.
Finish. Raw brushed titanium by default, or your chosen logo, custom graphics, paint, or anodising applied.
Delivery or pickup. Collect from the Melbourne workshop or have it shipped, ready to build up with your Pinion gearbox, drivetrain, and wheels.
Auren designs and builds in Melbourne. One workshop, one builder, frames made by the person you can actually reach.
Every Auren titanium bike comes out of a simple idea. Founder and engineer Will Young wanted to build custom titanium the way it should be done: a frame shaped around the rider, not picked from a range. Your geometry, your parts, your bike, designed with you from the first conversation to the final build.
Building direct means there's no dealer between you and us. When you're planning a build, talking through your fit, or need something sorted years down the track, you talk to Will, the person who made the bike. Every Auren titanium is built to last decades and backed by real support that doesn't disappear after delivery.
That's reflected in our reviews: five stars across Google and Trustpilot.
