Which has less mass, steel or air? On most planets, an air bladder is much lighter than a steel spring. There are other performance parameters, but air springs are light.

I ended up using the inexpensive crank, with high end chainrings, and top of the line bearings. Practical. Great tires, and that skinny Stans front rim. [more…]

The result became: Light, compact, and nimble, yet hard; intended for broken big city streets. Acceleration among traffic being a top priority for componentry harmony.
