Union Jack SRAM AXS Extended Chain Stabilizer Kit for Brompton Bicycle

SRAM AXS Extended Chain Stabilizer Kit with Oversized Pulley Wheels

• Weight: 139 g

Compatible with:

• SRAM AXS rear derailleurs only (other brands are not supported)
• Brompton G Line upgraded to 12-speed external gearing
• Brompton T Line upgraded to 7-speed external gearing

After converting a Brompton to a 12-speed SRAM AXS electronic drivetrain, the stock rear derailleur cage does not provide sufficient chain capacity. This extended derailleur cage with oversized pulley wheels increases chain tension to help prevent chain drops when folding, while also accommodating a larger cassette. It provides the dual benefits of improved chain retention and increased chain tension.
