Resurrected my On-One Il Pompino (v2 in Trigger’s Mum’s Bathroom Blue). This was my commuting bike for a 25 mile round trip for about 5 years.
Nitto Noodle bars, 48cm
Halo Aerorage wheel rear and a Mavic Cosmos front (from my first ever upgrade wheelset)
Nitto stem, fizik bar tape, Shimano Br-R550 cantilever brakes
Currently running 47t chainring and 16t/18t cogs and 16t freewheel, which I’m running now. 47×16 is a bit high for inclines and starting off, but actually pretty good on the flat (and the drivetrain is pretty efficient without derailleurs and a good chainline). I’ve got a lot of geared stuff in my parts box but running single/fixed is like coming home.
