The benefits of switching to a POLARBEAR chain guide are:

Thanks to its extremely low coefficient to friction, outstanding abrasion resistance, exceptional impact resistance, and self-lubricating properties, this chain guide is ideal for getting you through the gnarly stuff and is able to absorb a hit without bending like OEM or other chain guards.

When it comes to performance and reliability the POLARBEAR chain guide is a proven winner!

SPECIAL NOTES:
It may be necessary to break your chain to remove your stock or other aftermarket chain guide. If you are replacing a POLARBEAR chain guide block you shouldn't have to break the chain to remove or install it.
