I am happy with the choice I made. The Sirrus X 4.0 is a light and quick bike. I would have preferred a better component group set, compared to the Giant I was considering. So far the components are working very well, but will have to judge them after breaking the bike in more. I am impressed with Specialized. This is my second specialized bike. I purchased a MTB many years ago. It was also an awesome bike.

I bought the Sirrus X 4.0 and returned it within the 30 day window (Specialized with really good/fast with the return/refund, but the bike store tired to charge me an addtional fee, thankfully Specialized stepped in!). I liked the geometry of the Sirrus x 4, and for slow, level riding, it is very comfortable. However, if you go up hills, or increase the tempo in the slightest, the future shock and bars starts bopping up and down detracting from effeciency and handling. I actually felt unsafe with the Future Shock. The Future Shock is designed in a way that you are detached from the bars/steerer tube, so it is hard to gain leverage/torque on the pedals by pushing/pulling on the bars. With a normal fork based shock, you stay connected to the frame/pedals/bars so all the parts work in unison, but the Future Shock left me feeling out of sync with the bike.

Nice looking, easy to ride!

Purchased my first x4.0 six months ago and like every aspect of the bike. Relatively light and nimble and routinely ride 30 miles mostly on streets. The future shock and carbon fork absorb most bumps and the XL size fits my 6”6” frame well. I like the bike so much I just purchased a second one to keep at a lake house.

Great value for money

This bike is perfect for the trails , I changed my tires up to 42 mountain bike and wow what a bike ! Great for every experience! It’s so light with the carbon fork !

Really happy with the Sirrus X 4.0 in size Medium. I own and sold a Sirrus X 5.0 full carbon 2021 model and it was sweet bike but size large was too big. Medium is the sweet spot for me and I'm super happy to have a proper fit. This bike is agile and quick, love the future shock and SRAM drivetrain, my local Dealer CycleSmiths in Louisville, KY was knowledgeable and great to work with. I would highly recommend this bike for fitness, short to medium rides over mixed terrain.

I've come from a mountain bike but the truth is I bought the wrong bike and I don't really do the mountain bike stuff any more (if I ever did), it's all roads, trails and dirt tracks and it was hard work keeping up with my pal on his hybrid. I did not want a full road bike and the gravel bikes all seem to have drop bars which I don't want either - enter the Sirrus X 4.0 - straight bars and geometry that makes it feel sharp, a bigger 40 tooth chainring up front and a 11-42t rear cassette gives more speed than my mountain bike ever could. I've had it for a couple of months now and I love it, its quick to turn, fast, agile, I started modifying straight away knowing it was a keeper, EESilk+ saddle stem (makes the overall suspension perfect-works brilliantly with the future shock) and a SunRace MX80 11-51t cassette cassette just made the whole experience perfect for me, but it could not have been done without the Sirrus X 4.0 being a brilliant base bike right out of the box.

Best after sales service and quality bikes

I used to be an avid mountain biker...15 years and 40 lbs ago! I wanted to get back into biking and started looking at hybrids as I still had my old Stumpy and wasn't ready to make the leap to a drop-bar road bike. The Sirrus X 4.0 hit the sweet spot for me; comfortable but still pretty quick. Smooth and easy to ride. I had thought about tossing out some extra $$ for the 5.0 or maybe the 6.0 but at my riding level that was overkill. This bike has been great to get me back on two wheels. I took it out for maybe the 2nd or 3rd time and ended up doing over 26 miles - and it didn't even feel like it! I just came home because it was starting to get dark and I didn't have lights installed yet. I love this bike and I'm looking forward to many happy miles together. PS - I'm 62 years old and just recently started getting back into shape (riding my Peloton and dropping over 50 lbs) and this bike makes me feel like a kid again. I'm kind of obsessed...
