Had the first flat on Brompton today.

[Too many questions ahead - sorry] :)

Got out of the tube station ( Kings Cross ) - unfolded the bike and noticed the flat.

Do you guys fix flats yourself ? How often do you get a flat while riding in London?

I went to get it fixed to Evan's cycles and they charged me £21 ( 15 for labour and 6 for tube ) - feels a bit excessive.

Do you fix your Brompton yourself? How did you learn to fix your Brompton? Also what are best tyres for puncher resistance?
