Specialized Sirrus review

As you push yourself towards your fitness goals, you need a partner that you can count on, and we're happy to say that the Sirrus Sport fits the bill.

It's constructed from a durable, reliable, and lightweight A1 SL Premium Aluminium, and it features a bombproof assortment of components, like a Shimano Sora rear derailleur and powerful Tektro hydraulic disc brakes that are sure to get the job done.

Sprinkle in some added comfort from our proven Body Geometry components, like the grips and saddle, and a Fitness geometry that lives in the sweet spot between comfort and performance, and you have a bike that'll always be ready to go when it comes time to sweat.

Working with our Body Geometry team, we designed a frame that strikes the optimal balance between comfort and efficiency. The A1SL Premium Aluminium construction pairs weight savings with rugged durability, while the rack, fender, and disc mounts give you an incredibly versatile package.

The lightweight FACT carbon fibre fork provides a smooth, responsive ride, while the Plug + Play fender mounts give you the option to install rain-fighting fenders.

Braking duties are handled by Tektro hydraulic disc brakes to ensure effective, consistent, and reliable power through any kind of terrain or condition.

Top Bike

This is my first specialzed bike and I must say I am impressed , it's very lightweight and agile and fast , given that it does not feel flimsy at all when you encounter uneven road or cycle tracks , the micro shift system is precise and easy to use , and the hydraulic brakes ensure that you stop when needed ,yes the handle bars seen a little short if you are used to riding an mtb but after a few rides that's forgotten. Great bike , with fantastic set up and delivery by the Tredz team 👍

Superb

I've bought a few cycling accessories before now, that have been produced by Specialized and I've always been very impressed by the excellent design of their products. But this is the first ever Specialized bike I've bought, However, in my view, the Specialized Sirrus Sport Hybrid has all the hallmarks of the company's superb design philosophy as well as appearing to be very well made and very nicely finished. I'd originally been looking to buy a similarly priced Cannnodale Hybrid bike (to replace my current Hybrid bike which I use primarily for commuting), however, all the Cannodale's that I looked at, had rather 'heavy' looking frames which is very much in contrast to the the very 'slim' and elegant looking frames offered or provided in the Specilaized range of Hybrid Bikes. The only criticism I have of the bike perhaps, is to do with the Width of the Handlebars (which if you're used to riding a MTB especially), you might find - at 580mm with the Medium frame -possibly or slightly, too narrow. Otherwise I would thoroughly recommend this bike to anyone looking for a high quality, well-made modern Hybrid bike for all sorts of everyday use. The dark Gray one I've gone for looks great and the Medium Sized frame for my own 5' 8" tall frame is perfect.

Hybrid Sport Bike Guide

 

Hybrid Sport Bike Guide

Is a Hybrid Sports Bike Right for Me?

If you’re new to the cycling world, we highly recommend taking a look at our bike buying guide overview or our hybrid bike buying guide to help you decide what type of bike is right for your needs.

When you’re choosing a hybrid sports bike, there are a few things to look out for which can help you work out the quality and performance you can expect from a particular model.


Usage

There are a variety of hybrid sports bikes available. Some will have wider tyres and a suspension fork up front to take the sting out of rough roads and tracks, while others will have narrower tyres and a rigid fork for faster cycling on smoother tarmac.

Frame Material

Most hybrid sports bike frames are made from lightweight aluminium alloy or carbon fibre composite on some high-end bikes.

Aluminium

Aluminium alloy frames are strong and lightweight, especially compared to the steel frames on cheap supermarket bikes. Entry level hybrids have frames built from plain gauge aluminium while higher end bikes will feature ‘butted’ and/or formed frames which are significantly lighter and just as strong.

Carbon Fibre

Carbon fibre composite frames are even lighter than aluminium. These frames also offer a smoother ride thanks to the vibration absorbing properties of carbon fibre.


Fork

Hybrid sports bikes come in two basic flavours for riding different terrain. Road hybrid bikes are intended for riding on tarmac roads and cycle paths so will have a rigid fork. Mixed terrain hybrids feature a suspension fork for smoother riding on rough gravel tracks and forest paths as well as roads.

Rigid Forks

Rigid forks on hybrid bikes are usually made from aluminium alloy although you will find heavier steel forks on entry level models. Some high-end hybrids will have a carbon fork for a lighter, smoother ride.

Suspension Forks

Suspension forks are found on mixed terrain hybrids to help soak up the bumps on rough roads and gravel cycle paths. Suspension travel is usually just over 60mm, which is plenty for smoothing the bumps on rough roads. At the entry level, you will find coil springs with minimal adjustment. As you move up through the price points you will find lighter air springs and lockouts for more efficient cycling on smooth surfaces.


Components

What gearing options are there?

Most hybrid sports bikes offer a wide range of gears for taking on a variety of terrain. It’s not all about the number of gears though. This is because fewer gears on the front, combined with a wide range rear cassette are much easier to use, but still give you the same wide range of gears. As you go up the price points shifting gets easier with more cogs on the rear cassette and fewer front chainrings.

Hub gears are another option and offer a good spread of gears that require less maintenance to keep them running sweetly, especially when combined with a belt drive.

Entry Level Hybrid Bikes

Entry level hybrid bikes will have a triple chainset with a seven or eight speed cassette.

Mid-level Hybrid Bikes

Mid-level hybrid bikes will have either a double or triple chainset with a nine or ten-speed cassette. You will also find eight-speed hub gears at this level.

High-end Hybrid Bikes

High-end hybrid bikes with a rigid fork will often feature a compact double road bike chainset combined with a nine, ten or eleven speed cassette. Some suspension fork hybrid bikrd will have a single front chainring combined with a very wide range ten or eleven-speed cassette. Eleven-speed hub gears are also popular at this level.

Which are the best brakes?

There are three types of brakes found on most hybrid sports bikes

Rim Brakes

Rim brakes are powerful in the dry but are significantly less powerful in the wet.

Mechanical Disc Brakes

Mechanical disc brakes are powerful in all weather conditions. This makes disc brakes ideal for winter cycling as well as off-roading.

Hydraulic Disc Brakes

Hydraulic disc brakes are the most powerful in all weather conditions, and also offer the best braking precision.

Can I fit mudguards and racks?

Hybrid sports bike are practical machines, so you will often find models that come with mudguards and luggage racks ready fitted. All hybrid bikes are compatible with racks and mudguards, however, so you can always add them later if you wish.


Wheels & Tyres

Most hybrid bikes run on 700c road bike wheels as these roll most efficiently on the smooth surfaces. Occasionally you will find 27.5” (650b) or 29” mountain bike wheels on hybrids as these allow you to run higher volume tyres for a smoother ride on rough terrain.

Hybrid bike tyres are wider than road bike tyres, to give you more cushioning and grip, but not as wide as mountain bike tyres, so you can still ride efficiently on the road. Rigid fork hybrids have tyres with a low-profile tread pattern that is designed for all-weather cycling on tarmac. Suspension fork hybrids tend to have slightly wider tyres with a more aggressive tread pattern. These give you a little more grip on loose surfaces without slowing you down too much on the road.
