1. Discover largest entrance ring & largest rear cog.
2. Lay unthreaded chain over these sprockets.
3. Pull ends collectively beneath entrance derailleur - search for 1-link overlap.
4. Guarantee correct connection factors (inner-to-inner plate).
5. Minimize pointless hyperlinks utilizing a motorbike device.
6. Thread by way of derailleur & join ends cleanly.

And keep in mind: each bike is exclusive so whereas these steps offer you common steerage, seek advice from your particular bike’s handbook or seek the advice of with an expert mechanic if issues appear off-kilter!

Carry each ends of the chain collectively at a degree the place they virtually contact, then discover the closest hyperlink the place they could possibly be joined with out rigidity.

This is a useful tip: If you happen to’re changing an previous chain that was sized accurately, lay it out flat subsequent to your new one. Match up each chains hyperlink for hyperlink and use it as a information to find out the right size in your new chain. However keep in mind, in case your previous chain was worn out, it might need stretched barely over time which suggests you may have to take away a few hyperlinks from its whole size when sizing your new one.

For bikes with derailleurs, add two extra hyperlinks (one inch) to present sufficient slack for the derailleur to operate correctly. For single-speed or fixed-gear setups, intention for simply sufficient rigidity to maintain issues cosy however not so tight that it hampers motion.

To sum up:

• Thread by way of entrance ring and largest cog
