Most of the entry level bikes don’t offer stability and reliability in their services, especially when it comes to design. However, the Diamondback Atroz Comp Mountain Bike redefines “entry level” bikes. This is just because the bicycle comes with a great design which involves the excellent frame, saddle, suspension to forks.

To begin, Diamondback Atroz uses aluminum to provide much sturdiness. Aluminum is among the cheapest but rigid material. It is also light to make it easy moving around.

A slight difference is that the crank has only one chain slot for smoother operation. It also lacks a front derailleur making it significantly lighter.

The rear derailleur consists of the SRAM NX for better control. It’s SRAM NX 11 gear shifter makes it easier to change gears by allowing more space. The maximum gear ratio is 30/11 which has a direct impact on the top speed. The minimum being 30/36, therefore, climbing uphill can be tiring.
