30x20cm Brompton Bag Frame

30x20cm Brompton bag frame made of 3D printed PETG and carbon fibre tubes. Strong and sturdy enough for bags sized for this type of rack, typically up to 10L.

Weight is 120g compared to~240g for standard 30x20 bag frames. We spend so much on making our Bromptons lighter and sometimes forget that the accessories we attach on our Bromptons can also be more optimized!

This frame also does not have the "supporting lip" on the bottom of the frame. I have found that it is not necessary because bags this size do not sag much. I tested a bag with dimensions 30x20x14cm and didn't have an issue with the bag interfering with the mounted light on my Brompton. If you put a heavy concentrated load in the centre of the bag when the bag is empty you might have issues with sagging so it is something to be aware of.

If you need a custom size (larger or smaller), please send me a message before emailing and I can let you know if it's possible and any cost difference if any.

I have also added an option for Ortlieb Panniers due to popular demand

Colour of 3D printed parts are black by default.
