BOMBTRACK Audax AL Frameset - Splatter Silver / Black Fade

€998.00
Tax included

The Bombtrack Audax AL Frameset is an aluminium platform built for fast all-road riding, long-distance use, and light touring, with a full carbon fork, T47 bottom bracket, and modern geometry. In this Splatter Silver / Black Fade version, it keeps the same technical identity as the model: a responsive and efficient base for tarmac, white roads, and light gravel, with a character that leans more toward modern audax riding than pure gravel.

Bombtrack Audax AL Frameset

The Bombtrack Audax AL Frameset, in Splatter Silver / Black Fade finish, is designed for riders looking for a modern all-road frameset and also want an aesthetic that stands apart: an artistic, distinctive, and easy-to-read paint scheme, perfect for a bike built for real mileage. The technical base remains that of a contemporary audax bike: 6061-T6 aluminium, full carbon fork, modern standards, and a lively ride on asphalt and mixed surfaces.

Why Splatter Silver / Black Fade

  • Strong identity: a recognizable look, ideal for personal build projects.
  • Practical: the silver/fade mix tends to hide marks and dust well.

What the frameset includes

  • Frame: 6061-T6 double butted aluminium, thru-axle (TA), fender mounts, 86.5 mm T47 bottom bracket shell.
  • Fork: full carbon, TA, 1.5" – 1 1/8", fender mounts and cage mounts.
  • Headset: sealed integrated headset, 1.5" – 1 1/8".
  • Thru-axles: 12 × 100 mm (front) / 12 × 142 mm (rear).
  • Seatpost clamp: Bombtrack Prime 31.8 mm.

Where it performs best

“Fast & light” all-road

The Audax AL is designed for riders who want to maintain a high pace on imperfect roads and mixed routes: the carbon fork helps absorb road buzz, while the aluminium frame delivers a quick response, ideal for long and fast rides, randonnée, and all-day outings.

White roads, rough asphalt, light touring

The fender mounts and the mounting points on the fork make this frameset suitable for 365-day-a-year use: from fast commuting to winter rides, all the way to essential bikepacking with light bags. It is a frame that encourages you to move beyond perfect roads without turning the bike into a tank.

One project, two personalities (650B or 700C)

Within the stated clearances, you can build an Audax AL that is more wide all-road with 650B and generous tires, or faster-rolling with 700C for long distances on asphalt and compact gravel. The key is choosing wheels and tires that match the roads you actually ride.

Frequently asked questions about the Bombtrack Audax AL Frameset

Is the Bombtrack Audax AL Frameset a gravel frame or an all-road platform?

The Bombtrack Audax AL Frameset makes more sense as a fast all-road platform and modern audax bike than as a pure gravel frame. It is designed for long rides on asphalt, white roads, and light gravel, with a quick, smooth, and continuous ride feel.

What is the difference between the Bombtrack Audax AL Frameset and the Hook Frameset?

The Audax AL is more focused on fast long-distance riding, randonnée, and medium- to long-range all-road use, with a more direct aluminium platform. The Hook remains more clearly a fast steel gravel frame, with a setup more closely tied to compact gravel and white roads.

What tires can the Bombtrack Audax AL Frameset fit?

The frame and fork state compatibility up to 650B × 50C or 700C × 35C without fenders.

Is the Bombtrack Audax AL Frameset compatible with 650B and 700C?

Yes. In this case, the stated compatibility applies to both frame and fork: up to 650B × 50C or 700C × 35C without fenders.

Can you fit fenders and bags on the Bombtrack Audax AL Frameset?

Yes. The frame has fender mounts, and the full carbon fork integrates both fender mounts and cage mounts. This makes it suitable for light touring, fast commuting, and essential bikepacking.

Is the Bombtrack Audax AL Frameset compatible with 1x and 2x drivetrains?

Yes. It supports a 1x configuration up to 42 teeth with a 45 mm chainline, or a 2x configuration up to 50 / 34 teeth with a 43.5 mm chainline.

Is the Bombtrack Audax AL Frameset suitable for randonnée and long-distance riding?

Yes. It is one of its most natural use cases: it was created specifically as a platform for fast all-road riding, long distances, and light touring, with modern geometry designed for pedaling continuity and efficiency.

What technical standards does the Bombtrack Audax AL Frameset use?

It uses an 86.5 mm T47 bottom bracket, 12 × 100 mm and 12 × 142 mm thru-axles, flat mount brakes, and a 27.2 mm seat post. These are modern and highly relevant standards for anyone who wants to build a reliable and up-to-date bike.
