To attempt a cycling race, you need to be super athletic, and your chances of winning improve tremendously when you have a remarkable bike to ride you into victory.

My cousin, Glen, is currently training for his third racing event that is coming up in 4 months and the family conspired to treat him with a surprise bike.

I settled on two great options and thought it would be a useful reference to summarize their qualities to help guide the family’s decision.

Diamondback vs Specialized – How they compare

Frame and Geometry

Diamondback features an aluminum alloy frame and fork inferior to Specialized Tarmac bikes whichhas a Performance Road Geometry.

Diamondback has a steel steerer frame guaranteeing durability and resilience. This makes it ideal for hard riding.

The frame is made into an ergonomic design that stands apart from the competition and provides a strain-free, comfortable ride. 

The frame of the Specialized bike is built to be lightweight using FACT 12R carbon giving the bike a total weight of 6.7kg

There are two models- SL7 Pro and Expert, that have been designed using FACT 10R carbon and ride on the Di2 Ultegra set which makes the frame heavier by 0.6kg and 1.05kg respectively.

This series offers users up to 8 different models for both men and women but SL7 tops the charts by combining a lightweight, super-effective bike with aerodynamics.

There are varied designs across the Specialized series and your bike dealer should be able to help you pick out the right fit for you.

Features 

DiamondbackKenda tires are inferior to the Specialized sports 26mm tires that have a great grip on terrains of varied kinds and in all-weather conditions giving riders cornering confidence. 

You can ride at high speeds on this racer without fear of punctures or any risk of losing control because the bike has good handling. 

The double-walled rims provide comfort to the rider and protect the tires from damage. They are responsible for the bike’s balance and stability, especially at high-speed races. 

The brakes are Dual Pivot Calipers which are quick acting and they respond accurately to your commands. They are responsible for bringing the bike to a sudden stop with no tire locking or squeaky noises. 

For Specialized, the Roval Rapid CLX wheels and Aerofly II bars are great improvements made to this bike which make it 45 seconds faster than its predecessor the SL6.

Specialized Tarmacalso uses Shimano 105 groupset in 50/34 chainrings. However, the configuration is done with 11-30t cassettes which gives it an excellent setup.

As you can tell, there won’t be much significance in their ride difference because both seem to use the same company for their drivetrains and setups that are almost similar.

Ride experience 

Diamondback promises a smooth riding experience with stable control which is more reassuring than theSpecialized Tarmac which feels very light and cuts through the air with its superb stiff frame.

Gear shifting is done using Shimano STI groupset and this allows you to climb the toughest hill as fast as possible. 

With the ergonomically designed frame, you should experience no aches or pains after the ride and because it is lightweight, handling and control should be a breeze.

The Roval Rapid CLX wheels and Aerofly II bars are great improvements made to this bike. This makes the bike 45 seconds faster than its predecessor the SL6.

Verdict: So, which is better – Diamondback or Specialized?

The best racing option has got to be the Specialized bike range. This bike offers great speeds, control and maneuvers bend impressively. Did I mention how comfortable the saddle is?

While Diamondback also does well, it really doesn’t match up to Specialized features or benefits. I’d recommend the two bikes to lovers of a race but if you must win, go with the Specialized.
