Melvin Chain Tensioner

Description |

Paul Components Melvin Chain Tensioner lets you run a single speed setup on a frame with vertical dropouts by adding chain tension where a rear derailleur would normally mount. Melvin bolts to the derailleur hanger and uses two pulleys to manage chain tension and chain wrap, helping keep the drivetrain quiet and consistent. It also includes chainline adjustment via spacers at the mounting pivot, and the pulleys have side to side float to help handle small chainline variances.

Features |

• Mounts to a standard rear derailleur hanger
• Two pulley design provides 20 teeth of chain wrap
• Chainline adjustment using pivot spacers
• Pulleys use sealed bearings and allow 1 8 inch single speed chains
