ZTTO CG-04 Heavy-Duty MTB Chain Guide & Bash Guard — ISCG-05 / BB Mount

Core Shredder-Grade Protection.

If you're pinning it down technical descents, the last thing you want is a dropped chain or a smashed chainring. The ZTTO CG-04 is the ultimate insurance policy for your drivetrain, combining a rock-solid chain guide with a heavy-duty impact-absorbing bash guard.

Bombproof Drivetrain Security

Precision CNC-machined from 7075-T6 aluminium alloy, the backplate offers incredible stiffness and strength without the weight penalty. The high-impact nylon guides and bash guard are designed to take the brunt of rock strikes and logs, protecting your chainring and keeping your chain locked on through the roughest chatter.

Universal Fitment

Designed for modern enduro and trail rigs, the CG-04 features standard ISCG-05 mounting. Running an older frame? No worries—we've included a bottom bracket (BB) adapter in the box so it fits almost any MTB frame with a threaded BB. It's compatible with 1x drivetrains running 32T to 38T chainrings.
