My $30 fixie
it’s been well over 20 years since my last fixie, used to ride one to high school 
Old Centurion cro-mo frame, some bits from the shed, new chain and there you have it .
Running 42/16 on the old suntuor rear with roto fixed suicide sprocket. Currently running brakes F/R as I’m a chicken.
Added SPD pedals since pic and need another saddle but at least it’s probably not going to be stolen
been doing the commute to work for the last couple of weeks.
All’s good so far.

It’s much smoother to ride than my other bikes.
