Brompton mid stop block

Description

Allows you to roll your non-P-Line Brompton (ie. official C-line Bromptons and Bromptons before the C-Line designation existed) with the seat post up. Prevents unfolding when lifting the Brompton with the seat post up.

Features:

• Weight: ~10g
• Will fit with or without Brompton mudguard
• The standard colour is Black or Grey
• PETG.

Customization options (for an additional fee):

• Colour.

Some versions of this exist that are printed from TPU that rely on friction to fit but my model is printed in rigid PETG with a snap fit.

This fit on all frames (oldest bike I have tested this one was 2007) with some slight variation on tightness. I kept it on the tighter side because you can always sand it a bit to get it to fit better. The fit seems tight enough that it won’t rattle or fall off.

*I previous made the listing state that it was for pre-2022 Bromptons only but this was not true. I tested this on several 2023 frames and it fit perfectly fine.
