4 speed P line/T Line to 5 speed conversion
Convert your Brompton T Line or P Line 4-speed to 5-speed
After many years as a gold dealer for Brompton and living in Colorado, we decided it would be great to add a better climbing gear to the 4-speed Brompton, making life much better for its owner. Colorado is a mountainous and hilly state where every extra gear matters. Once we started making these conversions from the 4-speed Brompton P Line and Brompton T Line to a 5-speed setup, it changed the lives of our customers who opted for this conversion.
This is a great opportunity to improve your Brompton without all the extra weight of doing all the way to 12 speeds.
The conversion takes just over an hour. During that time, you can take a walk, have a coffee, or enjoy some ice cream while we breathe new life and energy into your Brompton.
Conversion kit costs $185 and includes:
Shimano CS-M5100
SRAM GX Trigger Shifter
For labor we charge $150 so you can convert 4-speed Brompton to 5-Speed for $325
