I might as well share my Electra alloy cruiser:
You can't beat Topline cranks with a titanium bottom bracket for ultralight:
I always use alloy BMX handlebars, (better seating position) and if I can find them, Cannondale aluminum Pepperoni forks. This one was threaded, so I used a blue alloy headset.
More 18-spoke wheels with Campy Tipo hubs:
Ok I'm going to try and restrain myself, let me know if you want to see any others.
These are my passion, I love these bikes!
