Bastion process
Distinctly Different
Distinctly different. Because it matters.
Details matter. Craftsmanship matters. Ride quality matters. Individuality matters. Meaning matters.
01
Consultation and Ordering
Every Bastion is built for a single owner. The consultation process is where that individuality begins to take shape.
Upon receipt of your deposit, you will receive your Amulet — a bespoke symbol of ownership and the first chapter in your Bastion journey. The Amulet grants access to your personal Design Portal, where every detail of your bicycle can be explored, refined and approved.
Choose from more than one million colour combinations across painted and raw finishes in gloss or matte. Personalise your frame with your name, initials or a meaningful inscription inlaid directly into the titanium. Every choice is rendered in photorealistic imagery, allowing you to experience your Bastion long before it exists.
The process extends beyond aesthetics. Components are selected from the finest offerings available, including groupsets from Shimano, SRAM and Campagnolo, wheels from Partington, Princeton and Lightweight, and performance upgrades such as CeramicSpeed drivetrain components and our own BC-01 SRM Powermeter crankset.
Every decision contributes to a bicycle that reflects its owner. Distinctly personal. Distinctly different.
02
Design and Engineering
Every Bastion begins as a blank sheet of paper.
Before a single component is manufactured, we create a detailed digital model of your bicycle, engineered specifically for you. Geometry, stiffness and handling characteristics are carefully refined to suit your physiology, riding style and goals.
Using advanced simulation software, we evaluate how your Bastion will look, feel and perform long before production begins. We then provide a comprehensive Engineering Report for your review and approval, ensuring every decision has been considered before the first component is produced.
Because meaningful difference is engineered from the very beginning.
03
Production
Every Bastion represents more than 200 hours of advanced manufacturing and meticulous craftsmanship. Precision technology shapes each component. Skilled hands refine every surface. Together they create a bicycle that is distinctly different in both form and ride.
Bastion lugs
The lugs are the unmistakable signature of a Bastion.
At first glance they define the bicycle’s distinctive appearance. Look closer and they reveal the engineering philosophy that underpins every Bastion.
Each lug is individually 3D printed in aerospace-grade Ti6Al4V Grade 5 titanium, creating forms that would be impossible to produce using traditional manufacturing methods. The resulting shapes are not only visually striking, but engineered to optimise stiffness, power transfer and ride quality.
Beneath the surface, a complex internal lattice structure provides exceptional strength while increasing stiffness and reducing unnecessary weight. Every detail exists for a reason.
Following printing and machining, each lug is meticulously hand-finished by skilled craftspeople. The result is a seamless union of advanced technology and artisanal craftsmanship.
Distinctive by design. Remarkable in execution. A difference you can see and feel.
Bastion tubes
Unlike most bicycles, the carbon fibre tubes used in every Bastion are not sourced from a catalogue. They are created specifically by us, and specifically for the way we believe a bicycle should ride.
Each tube is produced using a highly controlled filament winding process, where carbon fibre is wound layer by layer around a mandrel with precise control over fibre orientation and placement. This approach allows us to fine-tune the performance characteristics of every frame, balancing stiffness, strength and comfort with exceptional precision.
The tubes are engineered to work seamlessly with our titanium lugs, creating smooth transitions throughout the frame and allowing each Bastion to deliver its distinctive ride quality. By carefully varying fibre layups and modulus, we can further refine the riding experience to suit the intended purpose of the bicycle.
The result is a frame that feels as considered as it looks. Whether finished in transparent clear, candy tint, matte or paint, every tube reflects our belief that performance and beauty should never be separated.
Bastion frames
Bringing a Bastion together requires patience, precision and an uncompromising commitment to quality.
Once the titanium lugs and carbon fibre tubes have been prepared and inspected, they are carefully assembled by hand using a bonding process derived from the automotive and aerospace industries. Each component is positioned within a precision fixture and permanently joined using a rigorously tested structural epoxy selected for its strength, durability and long-term reliability.
The frame, fork and barstem are then post-cured to maximise bond strength and temperature resistance before entering the final stage of inspection.
Every Bastion undergoes comprehensive quality control checks, including detailed dimensional measurements and proof-load testing, ensuring every bicycle meets the exacting standards expected of a Bastion.
Because the details you never see are just as important as the ones you do.
04
Finishing
Every Bastion begins with a single owner. The paint process is where that individuality becomes visible.
Once assembled, each frame is meticulously prepared for paint. Hours are spent masking, sanding and refining every surface, creating the foundation for a finish worthy of the bicycle beneath it.
Our artisans then apply multiple layers of paint by hand, gradually building colour, depth and character. Some owners choose understated and timeless finishes. Others embrace bold metallics, pearls and bespoke graphics. No two Bastions are exactly alike.
Throughout the process, every detail is scrutinised. Every line, transition and surface is carefully assessed and refined. Not because it is easy. Because it matters.
The result is more than a finish. It is an expression of the owner and a difference that can be recognised from across a room. Distinctly individual. Instantly identifiable. Built to be admired, and built to be ridden.
Bastion Foundry
The Bastion Foundry is a place that didn’t exist.
We had to build it.
Located in Melbourne, Australia, the Foundry brings together advanced technology and artisanal craftsmanship under one roof. Titanium 3D printers, CNC machines, filament winders and a dedicated paint facility work alongside skilled craftspeople to create every Bastion from the ground up.
Most bicycle brands outsource tubes, machining, paint—or all three.
We chose a different path.
It matters where a bicycle is made. How it is made. Who makes it.
That is why every Bastion is designed, engineered, manufactured, painted and assembled in-house. Not because it is easier. Not because it is cheaper.
Because it matters.
The result is a level of integration, precision and individuality that cannot be outsourced. Every Bastion is built for a single owner, and every detail reflects our commitment to making a meaningful difference.
