Riding Experience

Morning Commute

I put on my cycling gear, fasten my helmet, and step out of my house to hop on my beloved Specialized Sirrus 2.0. The morning air is still a bit chilly, and I gently pedal, feeling the fresh breeze against my face. The comfortable seat of the Specialized Sirrus 2.0 keeps me relaxed. With both hands firmly gripping the double-butted alloy handlebar, I get into the rhythm of my morning commute.

The city roads are bustling with traffic, and pedestrians are in a hurry. Thanks to the agility and lightweight of the Specialized Sirrus 2.0, I effortlessly maneuver through the traffic. The constant change of traffic lights has me intermittently slowing down and accelerating, but I maintain a steady pace.

As I progress on my ride, I gradually get into a fitness zone. The Specialized Sirrus 2.0’s multi-gear shifting system allows me to adjust resistance based on the road conditions, adding challenge and intensity to my ride. I pedal, feeling the muscles in my legs working. Sweat soaks my sports gear, but my heart is filled with joy and contentment.

Continuing my journey, I encounter a slightly bumpy road. The comfort and stability of the Specialized Sirrus 2.0 allow me to handle it with ease. I adjust my posture and keep moving forward. Although the road isn’t perfectly smooth, each bump and challenge adds to the thrill of my ride. Finally, I arrived at my office’s doorstep.

Evening Commute

After work, I mount my Specialized Sirrus 2.0 again, riding into the setting sun’s glow, and embarking on the journey back home. With the traffic thinning, and the sky darkening, I follow the road’s illumination, continuing my way.

On my homeward commute, I feel the fatigue of a day’s work gradually dissipates. The Specialized Sirrus 2.0’s performance soothes my inner self and relaxes my body. Immersed in the cycling process, I find solace and peace.

The journey back home, though shorter, is still a source of joy. Amid the silence of the night, the sound of the bicycle wheels spinning becomes exceptionally crisp and melodious.

Finally, I return to my doorstep. This ride back home not only relieves my day’s fatigue but also highlights the unique charm of the Specialized Sirrus 2.0.


The Specialized Sirrus 2.0 is an exceptional fitness bicycle. It features a Specialized A1 Premium Aluminum frame, renowned for its strength, outstanding performance, and strong responsiveness. Additionally, its Hi-Ten steel fork provides robust shock absorption and decent cushioning. Its drivetrain combines a Shimano Acera rear derailleur and a Shimano Tourney FD-TY606 front derailleur, resulting in a 2×8-speed configuration.

Moreover, this bicycle is equipped with Promax F1 hydraulic disc brakes, ensuring effective braking for rider safety. Notably, the Specialized Body Geometry Fitness pedals and Specialized Body Geometry Contour grips make it convenient for riders to purchase, saving time and effort. The bike comes with RoadSport Reflect tires featuring a classic and versatile tread pattern, coupled with high-quality Endurant casing for excellent tire protection.

Specialized Sirrus 2.0 vs. Marin Fairfax ST 1

Marin Fairfax ST 1

These two bicycles share similar materials, both featuring aluminum frames, 700c aluminum wheels, and steel forks with good performance. However, the Marin Fairfax ST 1 is equipped with mechanical disc brakes, while the Specialized Sirrus 2.0 features hydraulic disc brakes. Hydraulic disc brakes offer better braking performance, but they are heavier and less convenient for maintenance. Mechanical disc brakes are lighter but have less powerful braking.

Additionally, the Specialized Sirrus 2.0 comes with a 2×8 drivetrain. Compared to the Marin Fairfax ST 1’s 3×7 drivetrain, the 2×8 drivetrain has a wider gear range and smoother shifting. However, the Marin Fairfax ST 1 has a higher top speed, reaching 38 mph. It also has a smaller stack/reach ratio, resulting in a more aggressive geometry for higher riding efficiency.

Specialized Sirrus 2.0 vs. Schwinn Super Sport

Schwinn Super Sport
Schwinn Super Sport

The Schwinn Super Sport boasts a relatively fast speed of 39 mph, and it features a larger head tube angle, measuring 71.5°. This gives it outstanding maneuverability. Additionally, its BB drop is relatively large, which lowers the bike’s center of gravity for more stability. Its tire width is 35c, slightly wider than the 32c tires on the Specialized Sirrus 2.0. Wider tires provide enhanced support.

Furthermore, the Schwinn Super Sport is equipped with mechanical disc brakes, offering decent braking performance and ease of maintenance. It comes with a 3×7 drivetrain, which has a limited gear range and less smooth shifting. Both of these bikes come with pedals and grips. The Specialized Sirrus 2.0 has Specialized Body Geometry Fitness pedals and Specialized Body Geometry Contour grips, while the Schwinn Super Sport uses Schwinn sport pedals and Schwinn ergo grips, both of which perform quite well.

Specialized Sirrus 2.0 vs. Scott Metrix 30 EQ

Scott Metrix 30 EQ
Scott Metrix 30 EQ

The Scott Metrix 30 EQ features an aluminum fork, while the Specialized Sirrus 2.0 comes with a steel fork. A steel fork has more weight and offers better elasticity with some shock-absorbing capabilities, whereas an aluminum fork is lighter but less elastic. The Scott Metrix 30 EQ has a speed advantage, reaching 39 mph.

It’s worth noting that the Specialized Sirrus 2.0 uses Shimano Tourney components, while the Scott Metrix 30 EQ uses Shimano Claris components. Claris is technically a road groupset, while Tourney is suitable for entry-level mountain and road bikes. Claris has a stiffer spindle and crank, with its bottom bracket fixed on the drive-side crank. In contrast, Tourney cranks use the older square-taper bottom brackets, which lack stiffness, but they have simple and affordable cranksets.

Specialized Sirrus 2.0 vs. CUBE SL ROAD SL


The CUBE SL ROAD SL features a carbon fork, which is very sturdy and provides strong rigidity. However, it can be prone to breakage when subjected to impacts from sharp objects. The CUBE SL ROAD SL uses a 2×11 drivetrain, offering powerful shifting performance. But this results in the CUBE SL ROAD SL being almost $900 more expensive than the Specialized Sirrus 2.0 since it utilizes the higher-grade Shimano Ultegra 105 components.

Furthermore, the CUBE SL ROAD SL has a certain speed advantage, capable of reaching 39 mph. Looking at the geometry, both these bikes have a stack/reach ratio of 1.49, although their BB drop values differ. The Specialized Sirrus 2.0 has a larger BB drop, lowering the bike’s center of gravity for a more stable ride, while the CUBE SL ROAD SL has a slightly larger headtube angle, making it a very agile ride.


This is our review of the Specialized Sirrus 2.0. It is an excellent fitness bike, offering a comfortable commuting experience, and we’ve awarded it a high score of 4.6. If you’re looking for more bicycle information, please check out our other reviews.
