Last few bits for Mrs.116 geared build

The Mrs is keen to do some longer rides but isn't up for it on her hackney cruiser (single speed track frame) so I'm putting together something a little more comfortable for long distance.

If anyone has the following it would be much appreciated... more on the budget side of things but could be swayed by the right parts.

Shimano/Sram 11 speed cassette.
Seat (I had about 3 ok spares I gave away in a zen attack which I now regret). If someone has something nice I would be tempted here.
Black alloy swept back handlebars.
11 Speed Sram rear mech.

Thanks all.

DM'ing you now re the mech...

Got some ragley carnegie handlebars.

£20

White Rolls San Marco . Some minor scuffs on the sides.
20 GBP (postage incl.)

@johnnywbike seat sorted now thanks to @thross, thanks for the offer though!
@broken_777 thanks. looking for something a wee bit cheaper... I through/gave away most the parts I'm asking for a while back and hoping so hoping to finish this build for beer/£10 a piece. I'll prob upgrade down the line if the Mrs uses it enough.

I have an 11sp ultegra 6800 cassette. 11-28. Fair condition £20 in SW15.

Sounds bang on, I'll see if I can ride out your way this week (bit of a trek - but what are bikes for right?). Thanks!

i have a san marco concor light, in holloway, not sure counts as nice.
also a 11-36 sram cassette

If @chrisbmx116 doesn’t want the San Marco concor light, I’ll take it off your hands. Can collect today..

Sorry @cornelius_blackfoot will be collecting this week.

no worries.
Hope the build goes well.

Cheers dude, she was made redundant yesterday so hopefully this'll cheer her up...

I'm in the last stretch on this build... 3 cans of terrible Halfords paint down and it's nearly ready to be put back together.

Still in need of:
Brake levers for flat bars (25.4)
A small front rack
Prob some pedals (BMX style, I may have some somewhere).
