Having read other reviews talk about the chain falling off. The SLX rear derailleur has a switch to loosen or tighten the chain. With the switch tightened, the chain does not come off. I LOVE THIS BIKE!!!

First problem right off the bat was constant dropping of the chain in the front derailleur. This would happen frequently when pedaling, a when starting to pedal after coasting a little. VERY annoying and downright dangerous. Took it to the shop, they did some adjustments and the problem persisted. Took it in again and was told that the front chainring wasn't compatible with the rear Shimano SLX M7100 derailleur. What??? Why would Specialized do this combination? My LBS said that I should upgrade the chainring as it isn't compatible with the rear derailleur and put on a new chain to solve the problem. Took my LBS's advice and over $100 later Guess what? Chain still kept dropping. Took the bike back into the shop. Was now told that the rear hub was failing and that was most probably what was causing the chain drop. (this could explain the loud "clunk" I'd often hear when pedaling). This bike is only 1.5 yrs. old. Had to upgrade my wheels ($1600). $$2500 bike now $4400.

So far I love the bike and the look of it, have it for over a year now and upgraded wheels to roval and the pedals to bloomslang platform. The only thing I didn't like much are the tires, I think they are a little noisy

I thought this was going to be a great alternative ride from my road bike and my gravel bike. Sadly, I don’t ride it much because the damn chain comes off the front chainring while pedaling. Happened again today….while leveling off from a mild little climb. Sometimes it happens while on a flat section of road (I only ride it on pavement). It is so freakin annoying! For this sort of cash this should not be happening. Got this bike in October 2021 and now have 588 miles on it. It’s a good looking bike, but a bit heavy in the rear for an all carbon bike. So, overall, it’s a “meh” bike.

My body struggles with drop bar geometry and prefers the flat bar set up on mountain bikes and road bikes. I have an older sirrus for the road and was excited to see the "X" series when it was introduced. This bike is a blast to ride and can go just about anywhere. I've ridden it on road, gravel, and some tame mountain bike trails. Even did Unbound 100 with this bike. Love the simplicity of the 1x drivetrain. Like others have said, some components could be better. I've upgraded my drivetrain to GRX cranks, Wolftooth chainring, and SRAM cassette and chain. Shifts better now than when I first got the bike. Also switched out the seatpost for the Roval Terra Carbon Seat Post. Well worth the money. Looking to upgrade brakes at some point. Future dream build: Sirrus X 6.0 or "Pro" - with SWAT storage in the downtube, future shock 2.0 (adjustable), 47mm tire clearance, and better components.

I've had my Sirrus X 5.0 for about a month now, put about 400mi on it. This is a great commuting, gravel and light trail bike. It's light and fast, very nimble. Now the downside.. For the price of this bike, you'd think you'd get a decent component package. Not.... Crank and Bottom Bracket creaked excessively on first ride out the LBS. A couple of tweaks here and there to the crank arms and BB the sound went away. A week later the creak came back. As for the brakes, $60 dollar brakeset on a $2500 dollar bike? Really? Mind you.... depends on your riding style, ME, I ride hard and fast and I need stopping power, not slowing power. So I upgraded to Shimano SLX 2 piston, carbon handlebars and seatpost. Drivetrain is next. Overall this is a awesome bike with good suspension, I would recommend to a friend. Frame and fork are super sexy. If you're looking for a fast fitness/commuting bike and are not component conscious, as I am, then look no further. Step up your component game Specialized

Love this bike, it was difficult finding one though. I also had problems with the chain dropping. I tried a few things that didn't work and ended up changing the chain ring after my LBS recommended that. Apparently the stock Praxis chain ring's "wave" design can cause the chain to drop off. I went with a 42t (wanted a bigger ring anyway) SRAM X Sync and that stopped the problem immediately. I've had a few 1x bikes but this is my favorite.

Overall, love the bike! Nice and light, good brakes, nice geometry for me. Only issue I have is with derailleur or shift lever, can’t seem to get it right. I either put too much or too little pressure and it advances 2 gears or not at all. I’ve never had this problem with any other bike, so not sure what’s going on. Jury still out as I haven’t had my new bike tune-up yet, another week or 2 for that.

Very fun bike. I needed a more upright bike due to back issues, and this fits the bill. It is comfortable, fast, and a joy to ride.

the color is superb gold orange very nice.fast, good on climb, took it on sm.gravel,dirt on the recreation *future shock was so good...(((bike just floated)))). I plan 2 add Ergon Gp3 grips w/horn. The grips tho r fantastic that came on it,I just need to tilte them up more. I went w/lg I'm 5"7 but longer legs, &arms but the reach seems ok. Seat is a race seat, very comfortable on a 2 hr ride.I will add new CrankBrothers Stamp peddles in Poly w/shorter pins .This bike won't disappoint 👌 its fantastic. I'm going to try to post on YouTube so you can see the color..just type in redwood specialized sirrus x5.0.
