Strong Build

HASA R5 Road Bike 2015 Shimano 21 SpeedOne of the best pieces of advice that I can give you is to always select a well-built bike. This advice remains constant for beginner riders and expert riders, for entry level bikes and professional bikes, and for road bikes and mountain bikes.

I am happy to tell you that the HASA R4 Road Bike 2015 comes with a 6061 aluminum frame, which is strong, lightweight, and responsive. This bike will support your weight as you ride, and will stand up to abuse from rough terrain.

The bike also has an aluminum fork, which efficiently absorbs shock so that you have a smooth ride at all times. The fork also ensures that you can easily handle the bike on uneven terrain, so that you do not lose control and injure yourself.

Good Gearing

HASA R5 Road Bike 2015 Shimano 21 Speed ReviewGearing is an important aspect of road bikes, as it determines whether or not you can let loose as you ride. In the case of the2015 HASA R4 you have a 3-speed Shimano front derailleur and a 7-speed Shimano rear derailleur, which work together to give you a wide range of gears to choose from.

You can also take advantage of the Shimano shifters, which allow you to change gears without any trouble.

Stable Ride

While it is important to focus on the gearing and frame construction of a bike, you should not forget to look at other aspects such as the rims and tires. Both of these components play a big role in your bike, and you should therefore, pay attention to them. The HASA R4 Road Bike 2015 bike comes with Innova 700c tires, and alloy double wall rims. These components allow for a stable ride on a range of terrain.


When it comes to comfort, you will be happy with the comfortable saddle and handlebars. These two components reduce fatigue during prolonged rides, while supporting your posture so that you remain comfortable throughout.

Easy Braking

Last but not least we have the aluminum alloy brakes, which guarantee reliable stopping even in wet and muddy conditions.
