New tyre and tube for back end of Brompton. LBS convinced me that Schwalbe tyres are better than Brompton own-brand, but they only go up to 85psi, rather than 100.
New rear-brake-cable, and chain, for Nemesis. Like an idiot, I thought I could just split the old chain, and fit a new one. But the new chain was too tight, (obviously, with hindsight - that's why I needed a new one) so I had to slacken it a bit by inching the rear wheel forward a smidge. Prolly still a bit too tight.
