Diamondback Century 5 Di2 Road Bike Carbon

The Century 5 tops out the Century line with a full Shimano Ultegra 11 speed Di2 kit, which brings its pro-tested technologies to a wider audience. An Ultegra Clincher Wheelset also adorns this beauty providing an extremely lightweight and fast rolling wheel option. This frame features internal cable routing, carbon drop outs, a tapered headtube, and of course, all Century Carbon frames are Di2 compatible.

Not every bike ride needs to be a race. Concurrently, not every road bike needs to be a a race bike. For many, a short leisurely ride or a long distance comfortable spin is preferable. For these riders, a comfortable geometry is key. For these riders, there is the Diamondback Century Road line.

Diamondback's Century road line is all about efficiency and endurance. The Century retains all the handling, geometry, and ride characteristics of our carbon Competition platform, with a slightly higher head tube height to put less strain on a rider's back and neck. This improves the fit for riders with marginally less pelvic rotation and core stability.

  • DB Road Advanced Tube to Tube (ATT) Carbon Endurance Road Frame with internal cable routing, Carbon Drop outs, tapered headtube, Di2 Compatible
  • Shimano Ultegra Di2 electronic drivetrain for smooth and exact shifting every time
  • Shimano Ultegra Clincher Wheelset for lightweight, fast rolling action
  • Shimano Ultegra Brakes for ideal stopping power

Love this bike, stiff, light and fast. The Di2 is awesome, I cannot fault it, the shifts are smooth and effortless. I did change out the wheels for some Velocity Deep v's for training rides because I wanted to save the Ultegra's for later. I would buy this again. I would recommend getting the firmware updated, I just did this with the shimano interface at home, easy peasey!

Excellent bike at a great price! - Feb 29, 2016

Thunder Bay, ON

I bought this bike last May when the exchange rate on the Canadian dollar was more favorable and it was a great buy. Like other reviewers I was concerned about purchasing a bike online that I had neither seen nor ridden but I have been extremely happy with my purchase. I am 5 ft. 11 in. and weigh about 200 lb. and have found the 56 to be a perfect fit for me and have not changed any of the parts. I am an avid recreational cyclist who typically rides about 300 km. per week Last summer I logged about 3500 km. on this bike and found it smooth and comfortable to ride. The compact gearing with an 11-32 on the back and 50/34 on the front has been perfect for hill climbing and maintaining top speed on the flats. I am very pleased with the ultegra componentry and wheelset. The Di2 shifting is a real treat! The newer version of the Di2 has the battery installed in the seat tube whereas on this bike the battery is mounted on the underside of the downtube where it does not interfere with the water bottle mounts. To recharge the battery you simply remove the battery and recharge it in the battery charger that comes with the bike. Last summer I recharged the battery once. Incidentally, the bike also comes with the special Shimano tool that is used to connect or disconnect any of the Di2 cables. I highly recommend this bike and look forward to riding it again this coming summer!

Fantastic endurance bike - Feb 26, 2016

5 out of 5 stars
Hillsboro, OR

Bought this bike early Feb 2016 and have about 250 miles on it now. Full Carbon and Ultegra package with Di2 does not disappoint in the least. I'm coming from a race-model with 2005 Ultegra, and this new set-up feels like a dream. I was pretty skeptical about electronic shifting, but I don't think I could ever go back to mechanical now. I love the endurance model- it keeps me significantly more upright, but really helps my body/back fatigue for longer rides (40+ miles). The extra gearing (I'm coming from a compact 9-speed) makes climbing hills a piece of cake. I have a few main hills I climb that usually take 20-25 mins to climb and I use to be out of my seat 60% of the time, and one time up would completely exhaust me. First time out on this Diamondback and I never had to leave my seat, and I climbed the hill twice just because I could! I'm someone who is prone to buyers remorse because I usually go cheap and wish I hadn't later. No buyers remorse here- this bike is the whole package. I highly recommend.

Fantastic Bike & Exceptional Value! - Feb 17, 2016

Kanata, ON

I have put on over 4,000 km on my Century 5 since receiving it in early May 2015. It is a fantastic comfortable, lightweight, well-fitted and fast endurance bike! As noted by other reviewers, I too was hesitant about buying on-line without ever trying (or even seeing) the bike. On top of that, from the web pictures I thought the somewhat garish bike graphics and external battery were over the top for my taste - however, after unboxing and seeing the bike in person I actually love the look - it has nice lines and it looks and feels fast. I don't even notice the battery unless I am working on the bike. I had previously taken many other top-tier brands of similarly equipped bikes out for extended test rides - the Century 5 has proven to ride as well or better than any of them - and it cost less than half the price of other Di2 endurance bikes!!! The Di2 has performed flawlessly along with every other component on the bike. On my checklist of Ultegra or equivalent level components, this bike met every requirement, with the Di2 being a very nice bonus. At this price the bike should be an absolute no-brainer. I had a professional bike-fitting done and needed a bit shorter stem - other than that, everything is stock and it has proven to be close to perfect for my needs and wants. I loved the bike so much that we also purchased a DiamondBack Airen 5 bike for my wife. It is similarly Ultegra Di2 equipped but with a women's specific frame - my wife loves hers as well.

Great Deal, Awesome Bike - Jan 11, 2016

Cedar Hill, TX

I purchased this bike as an early birthday present during the Price Point end of year clearance sale and got one heck of a deal. I've only been riding for about three years now and this is my second bike; the first being an aluminum framed endurance bike purchased at the LBS. It's a nice bike with a mix of Tiagra and proprietary components but boy I had no idea what I was missing. I was initially hesitant about purchasing a bike online, sight unseen, but decided to take a chance because the deal was too good to pass up. Diamondback does not have a big presence in the road market but they offer a lifetime warranty on the frame and ALL of the components are top notch. Most companies skimp on the crankset, brakes and or wheelset but Diamondback has included the FULL Ultegra groupset with the Century 5 Di2. The handlebars and seatpost are also carbon and not alloy. The Di2 is incredibly smooth. I did need help from the LBS to dial in the derailleurs but it was money well spent as I shouldn't have to worry about the shifting again. I installed Ultegra 6800 pedals and the stock bike plus the pedals weighed in at 17.05 pounds with a 58 cm frame!! I was on the fence for a couple of weeks before I pulled the trigger on this purchase and I couldn't be happier.

Excellent Performance, Incredible Value - Oct 26, 2015

Knoxville, TN

This is my second road bike, and it is a huge upgrade from my previous bike. I assembled it in 1 hour. When the battery was fully charged, I tuned the rear derailer placement in just a few minutes (really easy, see youtube) and I was off and riding. I cannot overemphasis how happy I am with this purchase. The di2 is amazing! This bike climbs and handles very well. I love the saddle, the aero handlebar, the light weight wheels and the compliant 25 mm tires. The brakes are really nice. I was a little skeptical about a DB frame, but it is really nice. It has a huge bottom bracket and some robust chain-stays, very stiff and efficient! I have 0 complaints. Excellent performance, incredible value.

Lots of Bang for the Buck - Oct 01, 2015

North Central, NJ

This is a very nice bike for the money. Electronic shifting is very precise, and the wheelset alone retails for around $700 (though you can pick them up on sale for about $500). Had to swap out stem (too long) and saddle (too narrow), but that's typical with new bikes. There's a very wide range of gears in the cassette, which is nice if you live where it's hilly (like me), but maybe overkill if you're in the flatlands. I'm 6 feet and the 58cm fits great.

georgetown, TX

I'm fairly entry level but have been enjoying riding this. This was my carbon upgrade from a few years riding an aluminum frame with Shimano 105. This bike's lightness, smoother ride and Di2 group made it a worthwhile upgrade, especially at this 'price point'! ;-). I'm around 5'9" and got the 54, but may need to get a shorter stem. I recommend this bike!

Tuscaloosa, AL

Was in the market for a road bike and saw this deal on July 4th blowout. After scratching my head and looking at some for the more pricey bikes decided to pull the trigger with money remaining in my pocket. Definitely made the right decision I'm 6'2" went with the 60cm, 58cm would have work also. In a month of ownership and 300+ miles on the saddle including a century this is a performance machine. Di2 is flawless only charge once. Some may be weary of the Diamondback brand but where can you get a full carbon setup except stem and Di2 for this rice its a no brainer. Quality, ride, performance, handling, and components I highly recommended this bike.

Ordered on Thursday, arrived on Friday. Put it together Friday night and gave it a 45 mile shakedown ride Saturday morning. Ultegra quality was first rate. Rode flats, climbs, and descents and no issues. If you are on the fence, don't worry, this bike can perform. I'm 5'8" and the 54 was spot on.

Fantastic Bike, Fantastic Price - Apr 13, 2015

Lehi, UT

Upgrading from a 2004 Specialized E5 Sworks. At first I was hesitant because Diamondback is not a big name (yet) in the road market, and there wasn't a lot of reviews online about the Century. But since it had all brand name components and an Ultegra Di2 gruppo, it seemed like a great deal. To get a similarly spec'd bike from Cannondale, Specialized or Trek would have cost well past $3500. With lightweight bottle cages and speedplay pedals, the bike is approximately 17.2 lbs using my bathroom scale. The wheels are fast and accelerate well. I am 5'8" and the 54cm fits great. The Di2 shifting is fantastic and one of my favorite features of the bike. Ride is smooth and handling great. I paid $2,200, and it was worth every penny.

north las vegas, NV

I was looking for a bike for a while. I had a podium 3 which was a good value for the price. I decided to buy this one as it has all ultegra di2 groupset, the price of that alone is worth more than the bike. It has all carbon construction and handles GREAT. I would highly recommend this bike and at this price you cannot lose. Best value in a bike I have seen.
