3,400 euros cheaper than the S-Works: The Specialized Crux 5 S-Level in detail

The Specialized Crux 5 takes no prisoners. This new race gravel bike aims to be nothing less than the fastest gravel bike in the world. Naturally, with such a superlative, many will be eyeing the top-of-the-range model with the S-Works label. But a spec variant just below that could well be a real hidden gem when it comes to performance. The S-Level option is brand new and replaces the Pro model in the range. It’s designed to let ambitious racers enjoy a high-end Crux 5 without the price soaring into figures that remain out of reach for unsupported athletes.

​Conclusion

It doesn’t have to be an S-Works! The Specialized Crux 5 S-Level is only slightly inferior to its S-Works counterpart in a few respects and is a proper race gravel bike: light, aerodynamic and fast. The sporty riding position and slightly improved ride comfort make it ideal for long gravel races. So if you can do without that last bit of prestige and are committed to racing, you should snap up the S-Level. - Jan Timmermann, TOUR editor

S-Level instead of S-Works

There’s no doubt about it: at 10,499 euros, it is and remains the Specialized Crux 5 S-Level In the eyes of most gravel cyclists, this is a ridiculously expensive bike. Compared to the S-Works, which costs 13,999 euros, it might even be a bargain. According to Specialized, the FACT 10r carbon frame weighs just 98 grams more than the FACT 12 frame of its more expensive sibling. The S-Level shares the key technologies with the Crux 5 S-Works, but is designed to appeal to a slightly wider audience. Anyone looking to compete in top-level gravel races should also be happy with the S-Level.

Radical lightweight construction

​For Specialized, a race gravel bike must be one thing above all else: fast! For the fifth generation of the Crux, the Californian brand therefore set out to tackle the legendary Unbound Gravel course to find out what could make the bike even faster there. The frame shape is reminiscent of a Tarmac SL8 – and for good reason. Aerodynamics played a crucial role in the redesign of the Crux. Specialized is one of the very few bike manufacturers worldwide to operate its own aerodynamics wind tunnel. Compared to its predecessor, the Crux 5 is said to have an aerodynamic advantage of 12 watts at 45 km/h.

Specialized has tweaked the seat angle slightly; it is now half a degree steeper. The reach has also increased by a few millimetres. Overall, the Crux 5 offers a fairly sporty riding position – even sportier than many endurance road bikes. Of course, the Crux is a race gravel bike and uncompromisingly designed for racing. Its inspiration from road racers is undeniable. Weighing eight kilos, this S-Level bike is around 700 grams heavier than our S-Works comparison model, but is still super-light. Apart from the third bottle cage under the down tube, Specialized has essentially spared the Crux anything that might add even a single gram of extra weight.

Speed without compromise

The Specialized Crux 5 S-Level shoots forward like a rocket. The acceleration brings tears to your eyes. Especially on terrain where there are frequent changes in speed, this saves energy in the long run. Specialized’s own Pathfinder tyres also play their part. They have a shallow tread pattern and roll along almost silently, even on tarmac. The rubber compound doesn’t waste a single watt, but isn’t the right choice in wet conditions. Under load, traction can be lost quickly, even when climbing over coarse gravel.

A heavier wheel-tyre combination might improve the Crux’s riding stability, but that was never the aim with this bike. Overall, the Crux 5 – even in the S-Level version – is designed for a very specific purpose. As a touring gravel bike for amateur riders, or even an adventure bikepacking machine, it is quite simply too uncompromising. That’s why Specialised also has the Diverge model in its range. However, the Crux has also been given a bit more stability as part of the update. This is achieved through a 0.5-degree flatter head angle and a slightly lower bottom bracket. The result is – relative to its weight – stable straight-line tracking at high speeds. Once you’ve got up to speed, the bike is almost impossible to unsettle and holds its line confidently. This is brilliant for long-distance riding, especially when you might be losing concentration a bit after 300 kilometres in the saddle.

Strengths and weaknesses
