Starting a build

Looks sweet, but what pray are those limpet things on the front and back, lights?

yep, knog frog, got them as a pair for £14 in Condor Cycles, only need to be seen by other in London, nothing special.

What bars as those? I'm after something that duplicates riding on the hoods, is that what these do?

Nitto RB-021 bullhorn drop, it's a pursuit bar but perfect for London and especially for skidding.

can you rephrase 'riding on the hoods' please? I don't quite get what you mean.
