The G3C chain tensioner by SB ONE with built-in damping minimises chain slap and reliably prevents the chain from dropping. With an internal hex, the damping can be infinitely adjusted to your riding style and your bike - whether " smooth" or " hard" is up to you. The special construction of the mount system guarantees a secure hold of the chain tensioner on the derailleur hanger, the high-strength aluminium alloy (EN AW-7075 T6) makes the chain tensioner durable and robust.
