 If Specialized Sirrus Sport doesn’t work out for you, then a number of other options from different manufacturers, with similar features are there. Let us compare them on the basis of their geometry and components. We will compare Sirrus to Giant Escape 2, Diamondback Haanjo, Treck FX3, Diamondback Insight 2 and Cannondale Quick 4.

Stack /Reach

Giant’s emphasis on escape comes through the measurements, giving a more Aerodynamic and stable ride for long haul.

The Sirrus Sport has a longer 563 mm stack for upright comfort and a shorter reach. The profile is a matter of taste as loss of speed may not be liked by some.


All the alternatives have the same wheelbase falling within the range of touring bikes including Sports Sirrus at 1056 millimetre. The Haanjo is approaching a cyclocross bike appropriate as an all purpose bike. The Giant Escape 1 Disc may border on a too relaxed ride for some.

Head Tube Length

All the bikes with longer wheelbase lengths fall into the touring range including Escape 2 at 1079.5 mm, a bike marketed for longer jaunts . The Ariel Mechanical Disc again stands out for a more nimble ride indicating its brand.

Chain Stay Length

Chainstay length gives the way to tweak your ride with a long distance for better climbing traction and a short one for greater power transfer. The Sirrus Sport  at 445 mm with all the bikes has what is expected for touring models. Fitness means longer rides and the manufacturers put on this aspect of the geometry.

Differences in Component

The major differences with these bikes is the types of brakes they have. The Haanjo and Insight 2 have mechanical disc brakes while the Quick 4 has V- brakes. All the others contain hydraulic disc brakes, superior for technical riding and Precision control at a high cost with more maintenance than mechanical disc brakes.

The Sirrus Sport has Shimano M315 hydraulic disc brakes for great sensitivity and crisper feel on the road. Although easy to set up, more force is needed with mechanical disc brakes with less precise control over them.

So specialized sirrus and a good bike are definitely a great option to try.
