Mods to my Brompton S-line

[Squirt01]

Slowly working through the upgrades, (Carbon bars, carbon seat post, pedals etc) I`m looking to with each small upgrade to make this lighter. Recently been looking at screws on A/express as well as a new chainring. Can I go from a 50T to a 48T with problems or do I need to switch the chain.

Anything else I can do ?

I replaced the standard 7mm handlebar clamp bolt with a titanium one from SJS. Mine was for aesthetic reasons as I wanted it black to match the colour scheme.

I think the simplest / best value weight savings are:
1) Seatpost & Pentaclip replacement - Carbon post with built in saddle mount
2) Titanium bottom bracket
3) Swap inner tubes to TPU, something like the RideNow ones from AliExpress (Avoid the Tubolito ones, they're overpriced)

A black aluminium bell?

Also, lose the Brompton pedals, the folding one especially is very heavy. I fitted a nice light pair of MKS removable ones to my wifes bike.

3 gram saving?

You'll not need to replace/shorten the chain if you’re going from a 50t to 48t chainring.

A new saddle will save you a bit of weight.

A carbon seatpost that long. Am I right to be wary?

I've been running H&H carbon seatposts for quite a while now with no issues. They do publish test / certification docs with them so at least they have done some testing. Not sure the same can be said for some of the cheaper offerings from Aliexpress etc!

On average, AliExpress parts are downgrades. In this, H&H is OK, again on average.
