Lots of fettling - seeing as it's been raining for more than 24 hours without a break here in Luton.
On Rebecca's single speed Brompton, I've been fitting the Kinetics 8 speed conversion. It all works, although I've found the chain fouls the rear triangle as it folds, so I need to get a slightly longer bottom bracket. Although whilst browsing for that, I've also seen some options for fitting a front dérailleur as well, which has got me planning more changes.
On the Circe Helios, I've fitted the Brompton front bag fitting I got for Christmas, so that I can carry even more stuff on it.
On my Planet X Ti Sportive, I've fitted another Christmas pressie, which was a USE Alien Ti seat post, which replaces the naff looking Alu one which was all scratched. It was a real pain to fit though. But it looks very nice & bling.
For the commuter bikes for myself and Rebecca, on a spare set of wheels for both bikes, I've sorted out and fitted studded Marathon Winter tyres, ready for when the snow hits, so I just have to swap the wheels over rather than risk breaking fingers trying to swap over tyres.
