Thanks
I do actually have a black Team Pro but it has steel rails (it's on the Hewitt, which is already pretty heavy). And you wouldn't believe the trouble I had to go to to obtain two 95mm leather grips!
The reduced weight is actually noticeable when picking up the bike, which you do quite a bit with a Brompton. Note for other mudguard strippers; the bike does not roll when folded because it stands on the rear tyre (which is jammed against the frame when folded) and you need two special parts: the cable fender disc and the C-type hook for the LH fork dropout. The mudguards are going back on after the Dun Run anyway, because it has to do a week in the North Pennines and a bit of workaday transport stuff, followed by the FNRttS on 20th August. Then it will be temporarily stripped again for the BWC, with no lights or dynamo hub to get it down to minimum weight.
Biggest indulgence: a Chris King 2Nut headset. I got Argos to face 1mm from the top and bottom of the head tube and the stack height is perfect - 5 threads left for the locknut.
