Southern California-based Black Market Bikes is introducing its four-inch full suspension dirt jumper prototype, the Killswitch.
"We worked closely with Pablo Tafoya in developing our Hammer-Link design, creating a our compact low profile suspension frame," pro rider and company founder Carter Holland said. "The Hammer-Link provides four inches of rear wheel travel while maintaining a stiff, flickable feel with short 16-inch chainstays and the lowest seat height of any suspension frame, period."
Handmade from 6061 T6 aluminium, the Killswitch prototype can be run single speed or geared.
