    Great bike for the price

    Love this bike. Very stable. Got very lucky that the bike shop had my size. Do not know if Specialize updated the newer model. But I have an aluminum frame and a carbon fork. Do not know if this comes with the newer model? Can’t beat the price .

    Would Recommend?
    Yes!

    Well rounded bike and has great value for the price.

    I use this bike to cycle around my neighbourhood for fitness and to go to the store. The shifters are responsive and reliable, and I haven't had any problems with the drivetrain. Note that the front derailleur requires a hard, two click press in order to shift properly. I was worried it was broken, but having come from shimano shifters, I just wasn't used to having to press the lever all the way back. The bike is very lightweight, and rides comfortably over gravel trails and wooden bridges. The tires are too smooth to reliably climb up gravel, but if you take it slow you can make it. Besides, if I really wanted to hit gravel I'd just switch tires since the fork can take it. I was so happy with this bike that I suggested my dad get one, he got the 2.0 and is also very pleased with it. The black paint is slightly sparkly when viewed up close, and from afar it has a nice stealth look with the red highlights that make it pop.

    Take care of this bike and it will serve you well.

    Great bike, I see a lot of complaints about the crank falling off. This is an OLD issue and was recalled by the company... not a problem anymore. If you take some classes or watch some free YouTube videos on bike maintenance, you can learn to take care of this bike and it's ""problems"" that people complain about... just learn to take care of your bike. This bike is fantastic.

    Luvin' this bike!

    My crank arm came off also. The pieces were all there, re-attached 5 then finished the last 20 miles and safely made it home. The good folks at the bike store were familiar with the issue and had a tech specially trained to repair it. Took it in on Wed, home on Thur and riding the on weekend. The bike store was apologetic. I have enjoyed riding this bike so much. I re-entered the world of cycling last May, 2020. Our rides are usually in the 20-30 mile range and a mix of inclines, flat, hills and mountain. I can always find a comfortable gear in the 18 compressed combo. I am in a sunbelt state and ride year round, just sweat more in the desert heat. The tires were ""meh"", upgraded to Continental Gator Skins and no flats since. Many of my friends have taken it for a spin and love it. The best comment came from one who said ""this bike rides itself!""

    Disappointed

    So excited buy a new Specialized bike after years. 1st ride it felt very nice and smooth. 2nd ride on my way home from a group ride the chain broke in pieces. Took it back to the shop to get a stronger chain. 5th ride the left crank arm fell off and I tweaked my back. Found out the bolt fell off somewhere on my ride. Took bike back to shop again and it sat there for 2 weeks. I got a new bolt and within a couple rides it got loose again. I decided to put Thread Tightener on the threads. Hoping this bike holds up during future rides.. crossing my fingers

    Love this bike

    Having read these reviews, I made sure that the bike had the recall issue addressed. I've had the bike for over a month and am loving it. Great fast ride, responsive brakes, overall, just perfect--exactly what I was looking for.

    Love this bike.

    Tight, precise shifting, excellent braking and body positioning as I want. Wheel and tires aren't as light and fast as my old road bike but I expected that. It isn't why and what I bought this bike for. I enjoy the bump smoothing carbon fiber fork too.

    There is a recall for a dust washer not removed.

    For those that are having an issue, there is a recall for a dust washer not removed from the bike when assembly. This is causing most the issues and recommending taking it in to have this fixed. I just bought mine and they pulled mine a part to verify this and was back together in about 30 minutes.

    Crank Arm Fell Off

    On my third ride, the left crank arm fell off. I had no idea this was a known issue until I came to this website to look up specs! I'm very disappointed in this purchase and worry that I'm in for several other manufacturing defects.
