Choosing The Right Trigger Shifter
Understanding The Basics Of Trigger Shifters
A trigger shifter is an essential part of a bike’s drivetrain that helps you shift between gears quickly and accurately without having to take your hands off the handlebars. The trigger shifter comprises a small lever that is mounted on the handlebars, which you push with your thumb or index finger to change gears.
Here’s what you need to know about the basics of trigger shifters:
- Trigger shifters operate based on the principle of tension and release. When tensions are created in the shifter cable, it pulls the derailleur to move the chain to the bigger gears. Releasing the tension causes the derailleur to move the chain to the smaller gears.
- Trigger shifters come in two main types – the 2x or 3x, with the ‘x’ representing the total number of gears on your bike.
- Trigger shifters have indicator windows that show the current gear number in use. Some models come with both right and left side triggers, although right side triggers are more common.
Types Of Trigger Shifters Available In The Market
There are two types of trigger shifters: the sram and the shimano. These types differ in design, gear technology, and overall performance. Here are the details:
Sram Trigger Shifters
Sram is a brand known for its innovative trigger shifter design. It utilizes a technology called ‘x-actuation,’ which makes for precise and consistent shifting. Here are some notable features of sram trigger shifters:
- Sram shifters have a light but definitive “click” feeling, providing tactile feedback for gear changes.
- They are compatible with a wide range of cassettes and chains, with a maximum of 12 gears on a single derailleur.
- Sram trigger shifters require minimal force to change gears, making them a great choice for people with weaker hands.
Shimano Trigger Shifters
Shimano trigger shifters are the most popular trigger shifter type, and they come installed as standard equipment on most bikes. Here’s what makes shimano trigger shifters an excellent choice:
- Shimano shifters come with two and three-speed versions, with 7 to 12-speed being the most common.
- Shimano trigger shifters require minimal maintenance, making them a reliable and long-lasting option.
- They provide more significant ergonomic options, enabling riders to comfortably change gears when wearing thicker gloves during the winter season.
Key Factors To Consider When Choosing A Trigger Shifter
Here are the crucial factors to consider when choosing a trigger shifter:
- Compatibility: Ensure that the trigger shifter is compatible with your bike’s derailleurs, cassette, and chain. Incorrect shifter selection can adversely impact your bike’s overall performance and speed.
- Gear count: Consider the number of gears in the drivetrain, with 7-12 being the most common.
- Ergonomics: Trigger shifters come in different shapes and sizes to match the rider’s preferences. Consider comfort and adjustability to get the perfect fit for your hands.
- Budget: Cost varies depending on quality and features, with high-end models costing significantly more than basic trigger shifters.
- Brand: Consider the brand reputation and past reviews to ensure quality and reliability.
Choosing the right trigger shifter should depend on your riding preferences, budget, and overall bike specifications. Ensure that you choose a shifter that suits your needs and provides a great balance between precision and durability.
Steps To Install The Trigger Shifter
Preparing The Bike For Installation
Before installing the trigger shifter, make sure you prepare your bike properly. Here are the steps to follow:
- Remove the old gear shifter from your bike. You can do this by locating the cable and unscrewing it from the derailleur.
- Wipe down the frame and clean any dirt or grime that may have accumulated.
- Make sure the derailleur hanger is straight. If it’s bent, it will affect the performance of your new shifter. You can use a derailleur alignment tool to straighten it out.
- Check the derailleur alignment and adjust it if necessary.
- Add some lubricant to the chain to ensure it’s running smoothly.
Installing The Trigger Shifter
Now that your bike is ready, it’s time to install the trigger shifter. Follow these steps:
- Remove the cover from the trigger shifter, which is usually held in place by a couple of screws.
- Slide the trigger shifter onto the handlebar and tighten it in place using an allen key.
- Thread the gear cable through the shifter and secure it in place using a cable crimp.
- Run the cable along the frame and through the derailleur, securing it with cable ties as you go.
- Adjust the cable tension using the barrel adjuster until the gears shift smoothly and accurately.
- Tighten any loose bolts and make sure everything is secure.
Testing The Shifter
Once the trigger shifter is installed, you’ll want to test it to make sure everything is working properly. Follow these steps:
- Shift through all the gears, ensuring that each one engages smoothly and without delay.
- Check the indexing of the gears to ensure they are properly aligned.
- Look at the derailleur as you shift through the gears to ensure it’s moving smoothly and accurately.
- Take your bike for a test ride and make further adjustments if necessary.
Congratulations! You’ve successfully installed your new trigger shifter and you’re now ready to hit the road or trails with confidence and precision.
