    Simple but we'll thought out

    I bought this as a town/commuter bike for my partner and I'm pretty impressed with it. Well thought out details and attention to detail. Single chain ring with wide range cassette drive train is good spec. Brakes are simple but solid. Only need to trim the bar width a little and it's really sorted. I might even jump on it over my other bikes from time to time.

    Excellent all-rounder

    Purchased for my wife. This has been a great bike for the road and gravel trails. It has handled everything with ease and my wife loves the sirrus. Used it on some long trails and she has had comfortable rides each time. Wouldn't mind one myself but with 3 bikes of my own already there isn't enough room.

    Excellent run around bike

    Purchased for my (short) wife as a bike she can use for fitness, heading to the shops, and then taking the kids out in a trailer attached to the bike. So far she loves the colour, the sizing is spot on (as recommended by Specialized), it was easy to get set-up to ride. She also loves the saddle and the overall comfort. Grips, which provide more stability and comfort, were also given high-praise. The gears however have almost immediately required adjustment, which was expected at some point, but disappointing it was so soon. Environmentally the box the bike arrived in was massive and a complete waste of empty space. They could have made it more effort to build the bike, but reduced the cardboard down considerably. Overall, my wife is very happy with the bike and expects to be riding more often because it's comfortable, it fits her well, and she's confident when riding it.

    Slick all-rounder

    8 months in, this bike has handled virtually everything thrown at it in all four seasons. Usage has been ~ 65% commute, 20% gravel (packed/rough), and 10-15% singletrack. Very comfortable geometry for day to day around town use. It makes you want to ride fast. For anyone taking their first steps into cycling as a hobby, this will be a familiar posture that will make getting on the bike easy and remove any intimidation. In my experience, you absolutely cannot get into an aero position on the bike without feeling squashed, but that's totally the point. It's a fitness/hybrid, and meant to be used and accessible for anyone - beginner or experienced. As far as it's condition, it is very robust. Everything is in great shape and looks brand new after a clean down, and the bike has been abused. It managed a winter season and salted roads very well - no signs of rust. Impressive. It looks the part, but not so flashy that you will worry about it being stolen when you look the other way.

    Great bit of kit.

    Does everything you could ask of it and a little bit more. Solidly built and exceptionally robust so far. Handles gravel, dirt paths and light mud really well. Only real cons is that full size mudgards are a pain to fit, and the top tube shape quite awkward for fitting things to. The customer service at Specialized is also exceptional. Had a few issues in shipping & assembly that delayed the bike by around a week. However the team bent over backwards to fix it.
