My roomie built up his 57cm raleigh technium with some Titec Hellbents, 48/17 with BMX freewheel and a MAFAC front caliper from the seventies. The wheels are Velocity DeepV's with twisted spokes and campy hubs. It's got some big ol' bmx platform pedals on it.
This ride is sooo friskin' sweet. I'm 6'2" so the setup is a bit small and the stout a$s wheels and aluminum frame make this thing light and stiff. The wide bars allow me to get up to speed super quick and then I can just lay the damn thing way over in corners. I wear my cleated shoes on it and drag them through the corners makin' a sweet steel on pavement sound and possibly throwin some sparks around.
I feel like how some long time biker guy must feel jumpin on a torquey small displacement dirt bike after spending long hours in the saddle of a large displacement freeway cruiser.
Any future fixie I build up must have a fully detachable faceplate stem for easy swapping of handlebars. Drops for the work commute and risers for the weekend.
Want to feel like a rockabilly knuckledragger? Flip those risers upside down.
