The 2021 Specialized Sirrus 2.0 Step-Through in Satin Cast Black is a unisex hybrid bike for riders who have places to go, people to see, and fitness goals to achieve. The 2021 Sirrus is built around a lightweight A1 aluminium frame. This step-through version makes it really easy to hop on and off the bike, especially if you have loaded panniers or a child seat fitted.

The Sirrus bike has been in the Specialized range for years but gets subtle updates and upgrades every season. The current version is lighter and comes in a wider range of sizes than ever before. At its core the Sirrus has always been a bike that is designed to be fast on the road while still being really stable and comfortable to ride. This makes the Sirrus really popular with commuters but also means it is a great fitness bike.

The Sirrus comes with reliable Shimano components that are built to withstand years of daily abuse on the world's pavement and ergonomically designed Body Geometry touchpoints to take the sting out of longer rides.

The Sirrus 2.0 is the second bike in the Sirrus range and comes with 16 speed Shimano gears and powerful hydraulic disc brakes that will help you stop in any weather. The tyres come with puncture resistance built in and the bike has all of the mount points you need for mudguards and pannier racks.

This bike is perfect for

Riders who want a simple lightweight bike for commuting or for reaching your fitness goals. With an extra two gears compared to the Sirrus 1.0, and with the addition of powerful hydraulic disc brakes, the Sirrus 2.0 let you ride, and stop, more quickly.

Key Features

  • Lightweight A1 Alloy frame with 42c tyres clearance, clean internal cable routing and mounting points for a range of accessories give maximum flexibility.
  • Step-Through design makes it easier to hop on and off the bike.
  • Intuitive and easy to use Shimano rapid fire 2x8 wide range gear shifting.
  • Powerful Hydraulic disc bakes for safety and control.

Why buy a hybrid bike?

Hybrids are the bikes that most people should have. If you want a bike for commuting, going to the shops, getting fit or just for getting around a hybrid is generally the best choice. They combine the speed of a road racing bike with the confident handling of a mountain bike to give you the best of both worlds.


Where are you going to ride?

The first point to think about when picking a hybrid is the kind of surfaces you will be riding on. There are two main flavours of hybrid bike. Some, like the Trek FX, Specialized Sirrus and Cannondale Quick are mainly intended for use on the road. They have bigger gears and skinnier tyres so that they are fast on tarmac. Other bikes like the Trek Dual Sport, Specialized Sirrus X or Cannondale Quick CX are designed to be used on a mixture of surfaces including tracks and gravel paths. They have bigger, grippier tyres and often come with easier gears and some suspension to soak up bumps.

Who are Specialized?

Specialized is one of the best-known quality bike brands in the world. Started by a group of riders in 1974. A fact which has guided their decision making ever since.

" Made for riders, by riders."

They strove to make the best quality tires when quality tyres weren't around. When people wanted to ride cruisers in the dirt, they made the first production mountain bike. When roadies wanted to go faster, Specialized doubled down on carbon and built their own wind tunnel.

Bikes like the Allez, Rockhopper and Stumpjumper have developed followings and reputations of their own. Specialized has a reputation for making high-end, high-quality bikes. Specialized bikes always look great with high-quality paint and sensible sizing hel0s you get the right bike each time. If you buy a Specialized bike you can be guaranteed it will do what it is supposed to and will last.
