The 2021 Specialized Sirrus 1.0 Hybrid Bike is a unisex bike for riders who have places to go, people to see, and fitness goals to achieve. Since 2020 the Sirrus has been built around a lightweight A1 aluminium frame. That's 1.1lb (.5kg) lighter than the previous generation of this bike. The Sirrus bike has been in the Specialized range for years but gets subtle updates and upgrades every season. At its core, it has always been a bike that is designed to be fast on the road while still being stable and comfortable to ride. This makes the Sirrus 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 long rides. The Sirrus 1.0 is the entry-level bike in the Sirrus range, and Specialized have kept things simple. It uses 14 speed Shimano gears, and tired and tested v-brakes. 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. As a unisex bike, the Sirrus is available in sizes to all kinds of riders.
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.
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.
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.
