About Diamondback

Diamondback built the rad BMX bikes that fueled the 80s boom. Their bikes are different (read: evolved), but today Dback still caters to an elite roster of sponsored pros, bringing performance and stoke.

Upgrades
- New PRO Components Koryak dropper seat post for downhill riding.
- New Maxxis Minion DHR II rear tire for grip in all conditions.
- Tuned front & rear brakes, firming up lever pull & creating consistent grab.

Master Mechanic's Notes:
- Small scratches on the top tube & seat tube.
- Light scratches & scuffs on the rear triangle.
- Small dent in the front rim.
