-550g weight loss

I replaced the standard 843g telescopic seatpost + pentaclip with Woodman Post GT2 Long Seatpost 600mm - 293g. The difference was 550g. Massive weight loss, I think this is the most cost effective upgrade I've ever done.

Major Brompton Update

The quality of the part is excellent! After replacing the seat post, the weight of the bike became less. Also non-slip design improved the grip. I highly recommend this upgrade!
