possibly posted already but this states ( 151 ) that drivers should be aware of cyclists filtering, aka ' undertaking' on the left...therefore 'undertaking' in slow moving traffic is not illegal ...just do it sensibly! -

Sturmey Archer 3 speed... thankfully I discovered my puncture at home and not on the road.
What a ball-ache these things are.
If ever there is a reason to get Schwalbe Marathons it is the hell that is changing a puncture on 3-speed Brompton.
Process is basically:
1) Undo gear cable
2) Undo bolt that gear cable runs through
3) Release tensioner
4) Undo bolts on axle
5) Release/Free holding plates (which likely are welded to the frame by grease and dirt)
6) Release wheelYou definitely need a decent pedal spanner for this. And that process in reverse is a fiddly thing (hope you didn't misplace the holding plates).
I'm far too used to just doing:
1) Release QR or bolts on axle
2) Release wheelEven on the Rohloff that is basically the whole process.
What has been an end-to-end 2-3 minutes to fix a puncture or replace a tyre becomes a 15 minute epic on the Brompton.
Oh, and you really need to have used the lower bolt on the gear cable connector to indicate position of the upper bolt, otherwise your gears are indexed incorrectly when you start riding again.
The more I use a Brompton the more I'm surprised that something so cheaply made actually works as well as it does. It's all about the incredible fold, but everything else is a sub-par experience.
Don't forget to cable tie the folding rear triangle to the seat tube before installing a Brompton in a cycle stand ! at the LBS that I worked at all Bromptons were dealt with this way (and before doing bunny hops up and down the shop floor)...most Brompton owners were unable to go through the complex engineering required to fix a puncture on their machines.

70 inch gear is about 'right', just below that suits me.

Anyone using the Midge bars (or similar) on their Pomp? I would be interested in hearing how you get on with them, pros and cons (and any pics of set up!).
My pomp is ridden as a ss cx, I have set them up with the lower bit almost horizontal, fit brakes highish on the curve; this works for me. I ride mostly on the brake hoods but when descending use the drops, the width is good for some feeling of control! Also I use a 90mm stem.

i wouldn't like to ride with that fork on again. it looks like its structural, where the alloy dropout is fixed into the carbon. not worth risking your front teeth over
the carbon fork leg should not catastrophically fail, carbon will go soft/bendy; as mrveg says the stress crack is where the drop out is bonded into the fork leg...it may be possible to repair this, worth asking around, maybe try Argos cycles in Bristol http://www.argoscycles.com/
