- Cling one finish of the chain on the most important entrance chainring.
- Pull the opposite finish in direction of your largest rear cog.
Now, discover the place they meet with some overlap — that is essential for correct tensioning afterward. Add two hyperlinks right here (one inside and one outer hyperlink), which helps in offering sufficient slack in your rear derailleur to function successfully.
Subsequent step includes threading the chain by way of your rear derailleur accurately. Totally different fashions have particular routing strategies so it’s important to test Shimano’s pointers or seek the advice of your bike guide. Pay shut consideration as incorrect routing can result in poor shifting and elevated put on.
As soon as threaded, pull each ends of the chain collectively beneath your rear derailleur pulleys. In the event you’ve obtained a more moderen mannequin with a clutch mechanism, ensure that’s disengaged earlier than pulling every thing taut to test for sizing once more.
After confirming that you’ve satisfactory slack (however not an excessive amount of), use a dependable device like Shimano’s TL-CN28 or related high quality chain instruments designed for 12-speed chains to separate any extra hyperlinks from the looped sizing information you initially created.
Lastly, I counsel utilizing Shimano’s really helpful connecting pin or grasp hyperlink which is specifically designed for his or her 12-speed chains — don’t combine and match right here as parts are made particularly to mesh nicely with one another making certain optimum efficiency and security on rides.
