Buyer's Guide: Dura Ace 7900 Crankset

Review of the Dura Ace 7900 Crankset

Shimano Dura Ace series of crank sets is one of the most popular. The company has been around since the early 80's and has been making quality bicycle components in Japan since then. Shimano has a reputation for producing quality components that last a long time, so if you buy a Dura-Ace set from them you know you're getting value for your money. If you want to upgrade your current bike but you have a limited budget there are plenty of options available.

The crankset on a typical dura-ace fc-7900 is made out of forged aluminum with precision cutting and precision drilling finished by a process called quenching. It also uses two kinds of technology; the first being the hollowtech technology which is used on the majority of the bike's chainrings. This technology allows the hollow aluminum to create a deeper, rounder crankset which, in turn, creates more strength. The second type of technology is the solid brass which is used on the spindle and the sprocket bearings. These two technologies complement each other and work well together to give you maximum strength and stiffness in every pedal stroke.

When it comes to crankarms there are basically three types of options. There are the open chainrings which are the shortest of the three and the lightest. There are the close tolerance open chainrings which are much heavier but handle much better in a variety of conditions. And finally there are the solid brass cranksets which, as you might guess, are the heaviest and most durable. However, all of these options have their downsides so it can depend on your riding style which one you should go for.

The Dura Ace 7900 Crankset has a standard full sized crank and it comes with either an open or closed chainface. For those riders who want a little more flexibility, the company has introduced the 'Integrated' design which allows you to use a wide range of compatible sprockets. This was first introduced in the Dura Ace 7210 crankset where there were options for both open and closed chainlines. Now this same concept is available on the Dura Ace 7900 Crankset where the open chainlines have been relocated to the closed ones. This move gives increased flexbility but it has also resulted in the weight being increased a bit.

One thing that we have found really useful on these cranksets is the fact that they feature a patented integrated topaz BMX headset. This is another great selling point as these headsets are designed to sit comfortably on the top of your head as it will reduce any vibrations that can occur when you are riding on the road. The headset also features a comfortable five-pronged hook and loop strap which should allow you to tighten and loosen the cable a lot easier than before.

With regards to the chainsets, Dura Ace have chosen to include some really good looking 'integrated' double bridging. As said earlier, this feature is only available on the Dura Ace 7900 Crankset but it looks very nice when you have it on. The double bridging is situated between the top and bottom brackets and the chainstays on the two ends actually run alongside the top and bottom brackets.

On the other hand, apart from the 'Integrated' concept introduced previously, this company has also decided to include their Dura Ace 7900 with a new version frame called the Superfly. This new frame has been designed especially for those people who want extra stiffness and support with their bikes. The main difference is that it is almost three times as thick as the original frames and comes with a new 'combi' technology. As a result, it comes with a new compact 110 bcd chainring and also weighs almost two hundred and fifty grams.

The last aspect of this bike that we would like to discuss is the crank arm. The reason why is because this is the area where most of the weight of a typical modern bike is placed. If you are going to be riding at a high rate of speed, then it is advisable that you replace the chain rings with something more powerful and heavy duty like the Dura-ace crank set. Although, we would like to recommend that you go for a Dura Ace crank set which is manufactured by another well known and experienced company such as Cane Creek. As a matter of fact, these two companies manufacture their own custom made cranksets and handle them with great care. Therefore, if you want your bike to last longer, it is advisable that you replace your chain rings with something stronger and more durable than the stock ones.
