  • For the right price, its hard to beat.
Style: Fastback Al 105 Size: 54cm/Large Frame
If you can get this at a relatively good price like I did it really is hard to beat. Its not without faults and initially it was a bit of a disaster, but it ended up being worth it (thus far) to me. First of all make sure you inspect the shipping box and bike itself diligently. I had to send back the first 2 I got for various reasons that made them unacceptable and they were all likely due to the shipping and the terrible boxes they come in (bent dropouts on carbon fork, faulty shifter, etc). I'm about 6' with slightly longer than average legs and I bout a size Large/54. I think it fits pretty well aside from a slight overreach. So im planning to replace the stem with a 80-90mm. Full 105! Great brakes (I actually prefer these caliper style to my disc brakes on another bike)! Cons: The saddle is pretty bad (in my opinion) Ive put some miles on it now and compared to my other bike it just doesnt cut it. Youll likely have some kind of cosmetic flaws on the paint somewhere, all 3 bikes they shipped me did. Its not a deal killer at a good price but it still kind of sucks. The cables are low quality and will likely be the first thing I replace in the future. Neutral: Pedals are included but cages are a bit dated and while you dont normally get pedals anyway with other name brand bikes with this tier groupset, regular flats would have been better. Wheels and tires arent terrible however they are a little heavy if you care about things like that and I had to put liners in cause my roads are pretty bad. Frame is good enough and honestly in person I think it looks better than online. I recommend you take it to a local shop if something seems off after assembly. ... show more

  • I love it.
Style: Fastback Carbon 105 Size: 51cm/Medium Frame
I highly recommend this road bike. I never owned a road bike before and the only other bike that I've owned is a hybrid commuter bike. I got interested in cycling in the summer of 2019 and started doing some research. I wanted something light, so a carbon fiber frame was a must. Most entry level carbon fiber bikes from the big brands (Specialized, Trek, Cannondale) are expensive, starting at around $2000, and I was hesitant to spend that much on my first road bike. When I found the Fastback Carbon 105, I was pleased with the price (I paid about $1450 on prime day) but also with the actual components (Shimano 105 drivetrain). I bought it in July 2019 and had my local bike shop put it together for me (just to be safe and make sure it was done properly). I now have about 1600 miles on it after 7 months and I am so glad that I made the purchase. The bike rides very smoothly and I have not had issues with any of the components. I use for rides ranging from 20 miles up to 90 miles and I always have a great time and a comfortable ride. I ride on flat terrain in Philadelphia but also on some hilly areas around the outskirts of the city. After having 1000 miles on it, I bought 50mm carbon fiber wheels from SuperTeam and Continental GrandPrix 5000 tires, which have made my rides faster, smoother and at the same time made my bike look even sleeker. I make sure to clean it well after each ride, especially now that it was carbon fiber wheels which are not as durable as the aluminum wheels it came with. In summary, if you are looking to get a carbon fiber road bike with great components and without having to spend $2000+, this bike is the way to go. As long as you have decent routes near your home, you will easily become addicted with cycling, get to to explore areas of your city you haven't yet, all while also getting a great work out. ... show more

  • Bike is great but assembly before delivery was not perfect
Style: Fastback Al 105 Size: 48cm/Small Frame
There is nothing wrong with the bike. However, whoever did the assembly did not do a good job preparing the groupset. I had to send it down to our bike shop here and spent an additional $80.00 to re-do the cabling and index the front and rear derailleurs. Other than that the bike is super fast and I was able to do 35MPH without having deep rims. ... show more

  • Muy buena inversión por mi schwinn fastback carbon 105.
Style: Fastback Carbon 105 Size: 54cm/Large Frame
Muy buen producto, la compra de esta bicicleta, la hice basada en su cómoda geometría, para evitar dolor de espalda, y efectivamente ha funcionado como quería, posee buenos componentes shimano 105, si eres de lo que le gusta bajarle mas peso a la bici te recomiendo un nuevo sillín, los ascesorios seatpost, handlebar, los compre de carbón, porque son de aluminio pesado, la gomas a menos que le pongas una cinta de Kevlar como hice pueden durar, pero en mis primera dos salidas, tuve pinchaduras, le puse la cinta y problema resuelto. Otra cosa pensaba que por su geometría sería una bicicleta perezosa, pero es bastante rápida y ágil, y considerando el precio es una buena elección, me gustó mucho y por eso la recomiendo. ... show more

  • Fantastic bike
Style: Fastback Al 105 Size: 48cm/Small Frame
The best bike for the price. Equipped with all Shimano 105 R 7000 components. Works great. Took only 30 minutes to assemble. Just get the front derailleurs fine tuned by some pro bike mechanic. Shifters work amazing. Very light weight. Mine also required some minor wheel truing. Spent about $50 on getting fine tuning done but was worth it. Amazon was super helpful in answering all the questions and concerns while making the decision to buy. Saddle is super comfortable. One last thing - if you are into serious bicycling you will have to replace original pedals with spd or spd-sl type pedals. ... show more

  • Great road bike!
Style: Fastback Carbon 105 Size: 51cm/Medium Frame
Love this bike! Sleek, fast and worth the price. I did get an open box and some things I had to take care of myself that you wouldn't otherwise have to deal with brand new but it made me a make shift bike mechanic and in the long run that's a good thing! The bike itself is stiff and a pleasure to ride. This is my first time on a true road bike and you'll have to get use to the ride but once you do you'll love it. I've already put over 300 miles on this bike. Only recommendation? Buy brand new and have a pro bike shop assemble it. These bikes need to be fine tuned. ... show more

What a steal! With the global bike shortage I can’t believe these bikes are in stock. I was looking at Treks but didn’t want to wait and this105 carbon is a better bike! What other 20 lb bike can you buy with Shimano 105 group set for $1200? The fit and finish on this bike is excellent. This is really a no brainer purchase. ... show more

  • Great Deal but some challenges
Style: Fastback Al 105 Size: 54cm/Large Frame
The large frame was a great fit for my 5'9" frame. The medium would have been too small. Read the sizing guides. Bike assembled was very easily. My challenges have been, rims needed to be trued and having a lot of problems with the shifting of the shimano 105 rear derailleur and alignment of the front. Hoping I do not have to spend too much money to get them functioning. The reason I bought the bike was the higher grade components, all shimano 105. ... show more

  • Schwinn Fastback Al105 size Large
Style: Fastback Al 105 Size: 54cm/Large Frame
I was actually never able to ride this bike. I paid a little over 900.00 for it-that money is a total loss. Originally I thought the problem was in the set-up. I took it to two different shops for a total of three adjustments. The bike would never change gears properly. I thought it was because of a bad rear derailleur. This past week I took it to yet another shop two hours from my home. (So far I have spent over two hundred dollars for mechanic work). The pro mechanic looked at my bike and said that he thought the Shimano 105 group set was fine. He looked over the bike carefully and stated that it was inferior. He told me the frame, wheels, hubs, and spokes was in his words "junk." He also stated that the problem could be in the cable, rear cog, or a bent derailleur hanger. He refused to take the bike as a trade, and was not interested in working on it. I have now purchased another road bike, and will pick it up next week. I began riding road bikes during my time in the Army in the mid eighties. ... show more

  • wheels are not good

i brought this bike in april of 2020, i gave it 4 stars at that time. but now i have to change it to 1 star. the reasons are in june back wheel broke 2 spokes was riding on smooth road, no heavy load called schwinn no answer but the message stated that i could email at customerservice@pacific-cycle.com so i did and told them about the spokes. i never heard back from them. if you were going down a hill when this happened you could get hurt the back wheel would not turn when the spokes broke. i took it into bike shop they repaired the two spokes. now on july21 this year another spoke broke. emailed schwinn again still no answer. this bike is not 6 months old rode mostly on flat roads with only a few hills. i can not say this bike is a safe bike knowing that if a spoke brakes and the wheel stops turning someone could get hurt. the bike 105 gearing works nice, changing gears works good. seat was too hard for me but that is nothing.i think schwinn should have answered either the phone call or 2 emails ... show more

  • Broke on my second ride
Style: Fastback Carbon 105 Size: 57cm/Extra Large Frame
The rear derailer snapped (the metal actually broke off) on my second ride. I had my Trek for 10 years, just got this new Schwinn, lasted 2 days. I called the support line, I was greeted by a very rude customer service person who did not even say anything like "sorry to hear you had a problem with your purchase," and immediately let me know that it must have been something I did. Funny, I rode my Trek bike on these same Maine roads for a decade, without a problem, and 2 rides in to the Schwinn it broke down. ... show more

I have 200+ miles on mine and it’s still a very clean ride and can hang with the best of them.. and I like to be noticed as different among the pack.
