Bastion Road Disc Brake Frameset

$10,449.99 Sale Save
Stiffness R (Regular)
Cable Routing eTAP

The ultimate all-round road bike. Powerful and efficient on climbs. Fast and confident on descents. So comfortable you won’t want to ride anything else.

The torsional stiffness and stability of Carbon Fibre. The ride comfort of Titanium. Our engineers have fine-tuned the ideal combination to yield a frame with the optimum balance of performance and mass. You will feel fresher at the end of long rides. You will want to ride longer. You will want to ride more often.

With framesets under 1,100g including the Integrated Seatpost, Rim Brake builds are possible under 6.5kg and Disc Brake builds under 6.8kg. The Bastion Road represents one of the lightest bikes in its class.

Completely custom geometry. Standard or custom paint. 3 flex options:

  • “R” Regular – for smaller, less powerful riders or those who prioritise low weight.
  • “S” Stiff – stiffer downtube and chainstays increases responsiveness with minimal effect on comfort.
  • “X” eXtra stiff – every tube stiffness is increased creating a frame that rivals the stiffest in the world.

All individually precision crafted just for you.

By combining Titanium and Carbon Fibre, Bastion bike frame technology gives you the best of both worlds, to create the best frame in the world. Our engineers have fine-tuned the ideal combination of Titanium and Carbon Fibre to yield a frame with the optimum balance of performance and mass. It’s the rider’s holy grail – a frame that blends the torsional stiffness and performance of a Carbon Fibre frame with the ride comfort of a Titanium frame.

The frame’s tube sections, which are the areas of highest deflection, use Carbon Fibre because of its renowned damping properties. However, in areas such as the bottom bracket, carbon fibre creates an overly stiff joint that compromises ride comfort. Here we use Titanium. Only the finest grade Ti6Al4V Titanium Alloy is used and the latest 3D printing technology allows us to form it into previously impossible shapes to create Bastion’s breakthrough frame design. We utilise the lower stiffness of Titanium to better isolate the high frequency vibrations of rough roads, whilst maximising torsional stiffness through asymmetric structures, transforming both ride and performance.

Our lugs are formed out of aerospace grade Titanium alloy powder. A specialised laser then fuses the powder to your exact specifications in a hermetically sealed, inert gas environment. The result is mechanical properties that rival those of forged parts. Our tube sections are wound layer by layer in carbon fibre over a mandrel in a computer controlled process called filament winding. This enables precise fibre orientation, continuous fibre paths, and higher fibre to resin ratios, giving you ultimate control of the performance characteristics of your bike.

Bastion’s bespoke design tool places our engineering know-how at your fingertips. It empowers you, the rider, to direct the design of your bespoke performance bicycle, allowing you to design, modify and then compare it against the world’s best. Next we validate your design, ask any questions and create a 3D model which is sent for your approval, together with a preliminary engineering report and the Finite Element Analysis (FEA) results.

Finally, on your go ahead, we begin manufacture. From 3D laser fusing to final painting requires over 130 hours of precision work by machine and 70 hours of meticulous hand crafting. We will provide progress updates and aim to deliver your frame with the final engineering report within four to six months of your order. If you are unsure about setting up your initial design simply contact us.
