Designed to provide drivetrain versatility, the 410 Chain Master Link makes customizing your chain easier than ever. With a wide variety bike being compatible with bicycle engines, installing your chain may require modification. This, in turn, will usually require you to break your chain in order to either make it longer in shorter. However, in doing so you will need an extra link to complete the chain. This is where the 410 Chain Master Link comes into play. Featuring a versatile design, this master link is able to be installed in between the break in your chain. Not to mention installation is easy, simply align the pinned section of the master link between the two broken links, install the oval-shaped end to complete the link, and finally install the clip to secure the link. So, whether you are adjusting your chain or repairing a damaged chain, you can trust that the 410 Chain Master Link has you covered.Package includes 410 Chain Master Link
Please Note: 410 Master Links are only compatible with 410 Bicycle Engine Kit chains. These are typically found on Grubee engine kits, but are not found on Flying Horse or Mega Motors engine kits.
