    Sirrus X 5.0

    Delivery Icon

    We deliver! Just say when and how.

    Offering an unprecedented combination of comfort, efficiency, and nimble handling, the Sirrus X excels on pavement, dirt, and any terrain in between.

    SMOOTH, COMFORTABLE, AND EFFICIENT: The patent pending Compliance Junction frame design of the Sirrus X provides the smoothest ride in its class. Engineered vertical compliance without sacrificing lateral rigidity translates to more comfort, control, and efficiency on all roads, paved or gravel.

    RIDER-FIRST ENGINEERED: Like all Specialized carbon bikes, the geometry of each frame is uniquely crafted. This means that for every frame, each tube size and carbon layup is specifically selected to achieve the optimal balance of rigidity, weight, and responsiveness to ensure that no matter what size you’re riding, you’re going to experience the world’s best ride.

    NIMBLE: Class-leading light-weight, exceptional pedaling efficiency, and steering precision merge for confident, nearly telepathic handling characteristics.

    Overall, really good

    I’d like to give this five stars but there’s a couple things that need to be improved to make it a five star review. Overall, this bike is excellent, it’s very smooth. It’s very comfortable and is perfect for what I was looking for. The ride is excellent, It’s smartly designed and is a big relief to my neck having switched from a conventional gravel bike. But I question the selection of components. They needed to do an upgrade on the drivetrain for better shifting and on the brakes for better breaking. I bought it for the carbon frame , knowing I was gonna make some changes to it, all virtual cost me probably $1000. I opted for this versus Any other similar bike because I have a specialized hot rod 29er mountain bike, which has been great to ride over the years. The shock that is built into the stem is plenty enough to dampen the little bumps along the way, and my shoulders and neck feel better as a result. I have to recommend the bike, it’s overall really nice.

    Fun, unrestricted, comfortable.

    1st impression from 7yrs on road bike, this bike is comfortable. Better visibility of traffic, looking over shoulder easier. Next thing it was like being a kid again with the wider tyres, cutting through parks, using shared cycle paths along the beach, exploring. Love the future shock, you have 4 settings, no sping, soft/med/firm. You have a choice to suit you. Was concerned about 1x. I have hills, some 8° +. The gearing for climbing was easy, sometimes easiest gear to slow. And on the flat cadence too big using 38T chain ring. Have tried 40T but have settled on 42T, that seems to suit me best. Thoroughly recommend. Only negative, I live in a humid place. I look after my bikes, cleaning and lubing chain regularly. Was disappointed chain was showing signs of corrosion and after 2 months bottom bracket as well. Quality of these a little disappointing but I did have Integra before. When I changed the chian ring needednew chain, got X01, problem solved.

    Great commuter

    I bought this bike to be my daily commuter and I love it. I have over 800 miles on it so far and it is holding up great. I am set up tubeless and have not encountered a puncture that could not be sealed. The compatible fenders work great to keep me dry. I have done a few gravel rides and that is when this bike really impressed me. The compliance junction does its job to soak up the bumps and the pathfinder pro tires have a ton of grip. The future shock does help but I think it would have been fine without it. My only complaints are of the choice of groupset. I regularly spin out and I have never used any of the low gears. I hope Specialized decides to put a proper crankset (not square taper and made of steel) with a 40t chain ring and a Sram XPLR groupset on their future models.

    Great all round fun bike

    I collected my new Sirius x5 in Spain last week & had the most amazing fun cycling the coastal walkways from Marbella to San Pedro. The terrain is a mixture of paved walkways & made up pathways. I’m a 60 year old man who has enjoyed road/mountain bikes for many years & i have now found an amazing fun bike with the new carbon framed Sirius ,

    Smooth and ultra comfortable

    My first carbon frame bike, and it is light and agile, but takes the bumps out of the road very nicely. The frame looks different, but feels strong. The future shock is completely unnoticeable, until you see the post area compressing consistently. I have ridden on roads I know well and that are bumpy, but this Sirrus X 5.0 smooths them out . Highly recommended.

    6 months later

    3,300 miles and 6 months later still loving my Sirrus X5.0. Tune up fixed my bent Derailleur Hanger and replaced my worn out chain. The ride was so much quieter and smoother with new chain(average mph slightly increased also). LBS was surprised how well the tires were holding up, very little wear for the miles traveled. I can’t wait to hit the road every morning.

    Impressive

    I was apprehensive in purchasing a "flat bar" bike after many years on traditional road bikes. I purchased the X5 about 2 months ago, the X6 wasn't available. I changed the tires to 28's, bottom bracket and crank to Rival 40 tooth, and the derailleur and shifter to SRAM Eagle GX AXS. This bike flat scoots and handles like a road bike. I highly recommend this bike even if you keep it stock.
