Chain Lines

The chain line is the distance from the center of the frame to the center of the chain ring.

All Jibb and Madonna frames are designed around a 52 mm chain line. If this is an option from your chosen drivetrain manufacturer, we recommend using this.

Using a 55 mm chain line on the Jibb and Madonna will work with the frame clearances, as the chain ring is further away from the frame, but it could have an impact on the performance of your drivetrain in the lightest gears.

However, this does not apply to SRAM Transmission, as this drivetrain is designed exclusively around a 55 mm chain line.

Yalla frames have a wider bottom bracket and are designed around a 56.5 mm chain line on SRAM drivetrains, like X01 DH, and 57.9 mm on Shimano drivetrains, like Saint.
