I bought my Sirrus X 4.0 back in June 2020 at the height of the pandemic. It was literally the only bike I could find in all of Houston in an XL frame and was way more than I planned on spending but after having my $400 Haro mtn bike stolen off the road after falling off rack before I could turn around and pick it up I desperately wanted a replacement. I found this bike. I read a lot about it before going to pick it up about the left crank falling off so I made sure to say something to the guys at the shop. They were well aware of this and actually showed me they had already fixed the issue and even put a marker on it that showed it was fixed. I’ve had this bike for almost 3 years now and I still love it. I have put a couple thousand miles on this bike easy and I really haven’t had any problems with it except for sometimes my chain has fallen off. It doesn’t happen a ton but it has. I plan to take care of this thing so it last for many more years to come!

Bought this bike to replace a 20-year old full suspension hybrid. The new bike felt like a feather. I put 100 miles in the first week. No issues. The left pedal did get loose somewhat, but not a big deal. The dealership fixed it. No issues so far. The Shimano Deore groupset is awesome. The breaks are excellent. People complain about brake noise, but they must have never heard of the brake part cleaner. Any any cleaner to that matter. Ignore bad reviews. This bike is awesome. We got tons of snow in VA lately. I keep riding my Sirrus X4 while I can't ride the road bike. Gravel roads, trails, towpaths, paved trails, parks. Everything. This bike is good.

I ride rail trails and back roads in my area and have been riding a Trek FX 3. My old bile was a little too large and I wanted to improve handling, performance, and efficiency, so I bought the Sirrus X 4.0. I am 5'7 with 29" inseam and the Medium fits me well. It is stable, agile and fast and it handles well on rail trails or pavement. The 1x11 drive train seems better than the 2x9. It shifts super fast and smooth and the 1x11 is versatile on any kind of hills or flat ground. I bought tubeless tires with light tread and they handle loose gravel well. This bike increases the fun factor and feels like it is part of me -- very natural feel. It met all of my goals an expectations.

After 200 miles on my 2021 Sirrus 4.0 X I'm thoroughly impressed with its capabilities. I started out doing mostly 15 mile road loops for fitness and found it nearly as efficient as a dedicated road bike. The riding position isn't particularly aero and the gearing spins out at 30mph, so I started to think about drop bars and gearing upgrades. But then I took it on some smooth single track MTB trails and was so impressed that I'm going the other direction with better trail tires. The bike rips on trails, and is much more efficient on rolling cross country trails than my 6 inch full suspension MTB. The 1x11 drivetrain. future shock and ergos of the bike are satisfactory for asphalt, but really shine on gravel and trails. Love this bike and I'm riding more than ever.

Great Bike. Owned it for a little more than a month. I started riding more miles with this new bike. Smooth ride and lite weight. Rode on Gravel and on paved roads. Performs Excellent! I used to ride a mountain bike, after two hours of ride, my thumbs feel numb, but with this bike nothing like that. Less stress on your hands with future shock 1.5.

I have enjoyed ride so far. Disappointed with Specialized and LBS where I purchased bike. I realized after purchasing bike right before shut down that my seat was 155. I have been measured in the past for specialized saddle and it was a 143. I asked to switch to the 143 size (listed on specs) Specialized and LBS said I would have to purchase a new seat to the tune of $100+ for same saddle. I wish I would have know before purchase. I am also going to contact LBS and ask about the recall of crank arm listed below. Jury is out as to whether or not I will recommend product.

I have had this bike for 2 weeks and love it. I exchanged the grips for Ergon3 grips that are more comfortable but other than that I have no complaints. Very light and comfortable ride. I can definitely tell the difference with the future shock and I am glad I spent the extra money to get that option.

This is my first real bike and what an amazing investment. It's comfortable and can do roads and gravel just fine. I took it on a 160-mile bikepacking trip last weekend and it was such a fun bike. It was my first time on gravel roads and I felt secure, comfortable, and fast! The tires are great for it and the Future Shock made the handling good. The only things I would or have changed are the handlebar width (which I think is a little excessive at almost 27 inches for a medium frame) and the saddle (which is always a personal choice). I did get it right after the recall and have had no issueS. The bike shop I got it at knew what they were doing and had fixed it already. I really enjoy this bike and I'm glad I got it.

I live in Laguna, we have tons of bike trails both paved and dirt. Lots of hills and lots of downhill twistys to ride. I had to wait to get my X 4.0 and it was worth it. My particular bike was after the recall so it wasn't an issue, but I think it was blown out of proportion. If you have any mechanical knowledge you know that two opposing bolts that are on the same shaft have to be torqued. If one is tighter or looser it causes problems. Maybe this was a bike shop problem... I don't know. Anyway, enough of that. I have put about 150 miles on the bike since I got it. I have taken it on paved trails, dirt trails, even a little mountain biking, It performed amazingly. The Future Shock does what it does without even noticing it's there, just smooth riding. I was impressed that there was no side to side wiggling of the handlebar which I thought would be an issue climbing. The seat feels great, the Pathfinder tires are amazing on all surfaces. It's light, fast, handles great, and climbs effortlessly. At this price point it's a super deal in my opinion. I have lost count as to how many Specialized bikes I have owned, they just do everything better.

My left Crank fell off on the 2nd ride. Took it back to the shop and they fixed it immediately. They also pulled it in for a recall on the same issue last week. Like a lot of you below, it's been in the shop quite a lot. Luckily for me the shop is willing to do all they can to help me out. My chain comes off pretty much every ride and I'd expect a little more. I do like the bike when it behaves!
