Specialized Unveils Crux DSW: The Lightest Alloy Gravel Bike Ever Created

Renowned for its innovation and high-performance bicycles, Specialized has once again pushed the boundaries of cycling technology with the launch of the Crux DSW. This latest addition to their lineup is a testament to their commitment to delivering cutting-edge bikes that cater to the needs of cycling enthusiasts. The Crux DSW is an aluminum version of the popular Crux gravel bike, boasting an incredibly lightweight and durable frame, courtesy of the patented D'Aluisio Smartweld (DSW) process.

The Craftsmanship Behind the Crux DSW

The Crux DSW is built using Specialized's D'Aluisio Smartweld technology, a method that sets it apart from traditional welding techniques. This process involves hydroforming, a technique that precisely shapes the bike's tubes to enhance strength and reduce weight. Traditional bike manufacturing often relies on heavier, bulkier joints that can compromise a frame's weight and durability. However, D'Aluisio Smartweld technology allows for meticulous control over the tube-to-tube joints, resulting in a frame that not only stands out for its lightweight properties but also for its exceptional durability.

The frame of the Crux DSW weighs a mere 1,399 grams, making it one of the lightest alloy gravel bike frames on the market. This revolutionary design ensures that riders can enjoy a bike that combines the robustness required for gravel riding with the lightweight build often associated with high-end road bikes.

Performance-Oriented Design

Specialized has long been known for their attention to detail and rider-focused design. The Crux DSW is no exception. It features the same race-oriented geometry as its carbon counterpart, the S-Works Crux. This geometry ensures that the bike is not only fast and responsive but also capable of handling the varied terrain that characterizes gravel riding.

One of the standout features of the Crux DSW is its impressive tire clearance. With the ability to accommodate tires up to 47mm wide, the bike allows riders to tailor their setup for different conditions, from rough gravel paths to smoother, more compact surfaces. The versatile design makes it an ideal choice for riders who want a bike that can perform in a variety of environments.

Available Options and Pricing

The Crux DSW is available in two main configurations: as a standalone frameset or as a fully built bike. The frameset comes equipped with the FACT 12r Crux carbon fork and is priced at £1,500. For those looking for a complete bike, the fully built version features the SRAM Apex XPLR mechanical groupset, DT G540 wheels, and Pathfinder Pro 700x38c tires, priced at £2,300.

In addition to offering multiple configurations, Specialized has also introduced the Crux DSW in a range of sizes and color options. This ensures that riders can find a setup that not only fits their performance needs but also their aesthetic preferences. The highlight colorway for the frameset is Gloss Amber Glow/Vivid Pink/Metallic Midnight Shadow/Speckle, a vibrant and eye-catching palette that is sure to turn heads.

Technological Advances Inspired by Previous Models

The development of the Crux DSW did not happen in isolation. Specialized drew on their extensive experience with the carbon S-Works Crux and the Aethos road frame to create a bike that inherits the best traits of its predecessors. This means that riders of the Crux DSW can expect a high level of performance and reliability, whether they are racing or enjoying a weekend ride on gravel trails.

Notably, the D'Aluisio Smartweld technology used in the Crux DSW is not new to Specialized. It has a track record of success in other models, such as the Allez Sprint. Peter Sagan, a prominent figure in the professional cycling world, rode an Allez Sprint using this technology during the 2019 Tour Down Under. His performance on the bike highlighted the advantages of this innovative welding process, paving the way for its application in gravel bikes like the Crux DSW.

A Step Forward for Gravel Cycling Enthusiasts

As gravel cycling continues to grow in popularity, the demand for high-quality, performance-driven bikes has increased. The Specialized Crux DSW meets this demand by offering a bike that is both lightweight and robust, capable of handling the rigors of gravel riding while providing a fast, responsive experience.

Riders looking for a new gravel bike will find the Crux DSW to be a compelling option. Its combination of advanced technology, performance-oriented design, and customizable options make it a standout choice in the market. Whether you are a seasoned racer or a weekend adventurer, the Crux DSW promises to deliver an exceptional riding experience.


The launch of the Crux DSW marks an exciting chapter in the world of gravel cycling. Specialized has once again demonstrated their ability to innovate and push the boundaries of what is possible in bike design. With its lightweight frame, durable construction, and versatile performance features, the Crux DSW is poised to become a favorite among gravel cyclists. For those seeking a bike that can handle the challenges of gravel riding while offering the performance of a race-ready machine, the Crux DSW is a game changer.
