Selling my Diamondback Century Carbon 4, a bike so pampered it has never touched actual pavement. That’s right: this beauty lived its entire life clipped into a trainer like some kind of carbon-fiber house cat. No potholes. No rain. No road grit. Not even a judgmental glance from another cyclist. Indoor miles only!

Highlights: • Full carbon frame that has only known the tenderness of climate-controlled indoor “riding.” • Components in near-mint condition — the derailleurs haven’t even experienced a real panic shift. • Zero crashes unless you count me nearly falling off the trainer once, which doesn’t affect the bike’s value, thank you very much. • Immaculate wheels that have rolled a total of… maybe 8 inches during setup.

Condition: • Basically new. • Cleaner than most operating rooms. • Smells faintly of ambition and broken New Year’s resolutions.

Needs new handlebar wrap.

Perfect for anyone who wants a great carbon endurance bike and the bragging rights of saying, “Yeah, it’s basically showroom condition.”

Buy it before I decide to actually ride it outside and ruin its pristine innocence.
