Hmm OK. I've loved commuting with dynamo on my sweet fixie so having it on the brompton seems great, but £200 for set plus new front light seems steep. What rechargeable lights are best for brompton?
You could just buy the wheel and the loom then buy your own lights. The standlight on my new style rear Brompton light failed within weeks so replaced with a b&m. (Which is better in every way and £10 more)
The whole SP setup adds around 250g (including standard lamps, front of which you’ll probably want to replace as its pathetic)
