Buying Guide

If you are looking to buy a new Shimano derailleurs group set, you need to consider a number of factors. Have a look. 


You can find the perfect derailleurs group set by considering the weight. If you’re riding in hilly areas, then it’s essential to choose a lighter derailleurs groupset. However, if you’re cruising around town or commuting on flat terrain, then heavier is better. The right choice will depend on your needs and preferences!


Brakes are an essential part of your bike, and it’s worth taking some time to think about what you need. There are many different types of brake systems available for bikes. There are two braking systems, rim brakes and disc brakes. If you decide to choose a disc brake, it will offer better precision and almost instant braking. In comparison, rim brakes press pad against the outer edge of your tire to stop. This provides a more comfortable braking experience in most cases.


Shifters are the devices that allow you to change gears on your bike, and they come in two different types – trigger shifters or grip shift shifters. Trigger shifters work by pressing a lever with your index finger to make gear changes, while grip shift shifters use levers mounted on either side of the handlebars that you can twist with your hands. Both have their pros and cons, so it’s important to consider which one will suit your needs best before making a purchase decision.

Speed setting

A derailleurs groupset with a lower number of speeds will be better suited to riders who are just starting or don’t ride as often. The higher the number of speeds, like 11-speed transmission groupset is meant for the more experienced and mountain active rider
