Somewhere I did a breakdown of where the weight savings are in the "superlight" models.   Naughtily, a non-trivial amount is from the omission of the pump, and you'll need to carry some sort of inflation device unless you live in the city and are willing to flag down a taxi or walk to the nearest tube/bus stop.

Where did you get your stats for the ti & steel fork? I got those from the Brilliantbikes website, according to whom it would seem the ti weight saving is less than you'd figured.

I think I weighed them both, since I upgraded.

Anyone here got a Brompton rim handy to weigh? I've noticed some double-walled 28H 349 rims appearing on ebay recently claimed to be 300g so options appear to be increasing, comparative weights would be useful.
