TypeHybrid Bike


Specialized Sirrus 3.0 is a more powerful version of Specialized’s workout bike with a slightly more “do-it-all” mentality. This bike is as maneuverable on back roads as it is for bombing through town or getting you to work thanks to its wide wheels and tyres and riser bar from a mountain bike. On prices, there is, nevertheless, some fierce rivalry.

The Sirrus line of bicycles are hybrids with slick tyres, a 2x chainset, and either a compact or step-through frame.

Even with the tyres pumped up firm, the ride quality isn’t horrible for what is essentially a budget aluminum alloy frame and fork. Although I found the lack of hand positions that a flat bar brings weird and something I must admit I’m not used to, it handles rough terrain nicely, and I never felt like I was being pounded.

Frame & Geometry

The fork is constructed of Carbon fibre, while the frame is built of excellent-quality Specialized A1 Premium Aluminum. The frame, on the other hand, has every feature a hybrid bike would need, including eyelets for mounting mudguards and pannier racks if desired. 

In comparison to the Specialized Sirrus 2.0 model, the Carbon Fact 9 fork is more comfortable and weighs 1.2 kg less.

The geometry is fairly relaxed on a bike of this kind, which puts you in an extremely upright position. In contrast, I felt that it was a touch too relaxed, causing me to sit rigidly upright and slowing me down—not good when you’re running late for work.


The Specialized Sirrus 3.0 has a 9-speed, entry-level mountain bike groupset called microSHIFT R9 that handles all of the shifting. This has an 11-34t cassette and a Forged aluminium arms, 2-piece, 24mm spindle, 46/30T crankset, which provides more than enough gearing to handle some quite steep hills on both the uphill and downhill sides.

The shifting is actually more than adequate for such a groupset. The front and rear derailleurs are both MicroSHIFT, which are incredibly dependable and precise. I rarely needed to give the thumb shifter more than a little prod to start the chain moving.

Brakes, Rims and Tires

Specialized Sirrus 3.0 comes with Tektro HD-R280, hydraulic discs. model comes with TRP Flow Set Control brakes as an option.

Except for the V-Brake, which uses 700C Rim brakes, all Specialized Sirrus models have 700C Disc rims.

The Sport and Disc models of Specialized Sirrus 3.0 comes with the the Specialized Nimbus Reflect tires
