Lightweight Upgrades for My 4-Speed T-Line – Suggestions?

Hi everyone,

I live in Istanbul and own a 4-speed Brompton T-Line. I’ve made a couple of upgrades already — removed the mudguards and swapped out the seatpost and saddle. The bike currently weighs around 7.3 kg.

Because of customs restrictions in Turkey (no overseas orders above €30 allowed), I plan to order some parts while I’m in Denmark this November. Here’s what I’m considering so far:
1. Extralite UltraLevers 3 – link
• Original T-Line brake levers are around 78g, these are 48g, so about 60g saved.
2. Extralite HyperGrips – link
• Estimate around 20–30g saved.
3. H&H Tensioner – link
• Around 38g saved.

Other thoughts:
• I’ve considered wheels, but they’re expensive and don’t save much weight.
• I’m also looking at eeBrakes, but I don’t think Brompton-specific versions are out yet.

Question:
Are there any other meaningful weight-saving upgrades you’d recommend for a T-Line?
I’m trying to be smart about cost vs. weight saved — open to suggestions before I place my orders in November.

Thanks in advance!
