Specialized Sirrus Carbon Review

Forgiving, flexible, and quick enough to move at the speed of life.

The next generation of lightweight, performance, and comfort.

Lightweight, comfortable, and nimble. The Specialized Sirrus Carbon is equally at home slicing through the city streets as it is roaming distant hills.

Specialized Sirrus X Carbon

The Future is a Feeling

Comfortable bikes aren’t usually known for their speed and manoeuvrability, but this isn’t a usual bike. 

With its unique double diamond carbon frame, and future shock suspension the Sirrus Carbon offers uncommon levels of comfort. And nimble handling with almost effortless acceleration.

Compliance Junction

The most striking feature of the Sirrus Carbon is the compliance junction. This is what makes the ride feel so smooth in the saddle. It’s designed to offer just the right amount of flex and forgiveness without sacrificing performance and efficiency.

Specialized Sirrus X Carbon Future Shock

Future Shock

Less obvious to the eye is the Future Shock suspension, located inside the head tube of the Sirrus Carbon bikes. This unique design prevents harsh frequencies caused by bumps in the road from reaching the handlebars.

Specialized Sirrus Carbon Frame

Optimized for You

Every Sirrus Carbon frame is Rider-First Engineered™ so features a size specific tube size and carbon layup. 

This ensures that every rider experiences the same ride quality. You get the optimal balance of rigidity, weight and responsiveness, no matter what size bike you’re riding.

Beyond Gender

Specialized’s philosophy is simple: don’t make a difference where there isn’t one. Because body proportions vary as much within a gender as between them. Sirrus is a shared platform for all genders.

The Sirrus X Carbon has more  robust wheels and wider Pathfinder tyres that make it more suitable for off-road paths and gravel tracks. Optimized for riding on tarmac surfaces the Sirrus Carbon has narrower tyres.

Responsive handling, lighting quick acceleration, and a comfortable ride. The Sirrus Carbon is a lightweight bike that rides like no other.
