Is there a Brompton parts weight database? I have been looking now for quite a while and
I'm getting weights that are all over the place and vary by vendor for the same part.
I realize that there are different models over the various years and such, but the simple process of trying to compare stock seatpost weights
has been much more of a donnybrook than I would have ever expected.
Sorry to be so dim, but I am not finding this using multiple search capacities.
I feel like I'm going to find it easier just to take the bike apart weigh things

There is this.

We have a thread in the German Brompton-forum where we have been collecting parts weights for some years now. Be warned that it is not structured in any way and obviously it is in German (google translate may help). It turns out that most parts vary a bit in weight, sometimes caused by different model years, sometimes maybe by different scales, sometimes variation in production.

Aftermarket parts you would substitute for the original ones to save weight ,
their low weight is a selling point so would be stated (y/n)

So this is about what the original factory ones weigh?

I recommend you to swap EVERY parts if you aim to save weight. The only exception is the rear suspension (the original rubber one is lighter than almost ALL aftermarket ones)
