The Brutal Engineering Rock Bottom High Pivot Chain Guide is designed for Enduro and DH bike frames that feature an idler pulley on the high pivot that the chain rides on.
The high pivot guide arm is angled to capture the chain at the tangent point of the chainring.
The guide is adjustable radially for 38t chain rings and fewer.
The chain guide features our Slap Guide technology. The harder your chain whips, the more it is pushed back toward the center of the chainring. We engineered the chain path to tight clearances which leaves no room for the chain to disengage from the chainring.
The guide features spacers ranging from 0.25mm to 5mm which allow precise chain line alignment to minimize rubbing.
The chain guide features flexible wings that absorb chain energy to dampen chain motion on rough trails.
The front of the guide is stiff to keep the chain locked dead center on the chainring.
The rear of the guide is bolted to positively capture the chain and restrain vertical chain movement.
Includes all mounting hardware.
