Replacement Hinge Spindles for Post-2004 Main Frames - Length 55mm
- Made from the same stainless steel as factory spindles
- Length 55mm, see further explanations below
- Available in 4 diameters, 6.0, 6.1, 6.2, and 6.35mm, see further explanations below
Please note that Brompton redesigned the main frame and stems along with the hinges in 2004. Some of the bikes produced during 2004 may still have the older type hinges. Please make sure the type of hinges you have and choose the correct spindles. See photos.
The original spindles fitted in the factory are 6.0mm in diameter. Unless the hinges were in good condition before being taken apart (carefully) for example for repainting, it is likely that a new larger diameter spindle is required upon re-assembly.
We have spindles available in 4 diameters:
6.0mm – choose this when there are no wear/no play in existing hinges
6.1mm – choose this if there is a small play in existing hinges
6.2mm – choose this if there is large amount of movement in existing hinges
6.35mm – choose this if previous smaller diameter spindles were installed and have again worn.
When the hinges are worn, usually they are not worn evenly. In order to use a larger diameter spindle, the entire hinge bore must also be enlarged, using a same size drill bit. We have the drill bits available here
If you have questions regarding spindle selection, please feel free to contact us.
