Say hello to my little friend. The first rule about project Killswitch is you don't talk about project Killswitch… I guess that's out the window now. We've been quietly working on our suspension frame ( you know the name now.) for almost 2 years now, slowly defining our thought of a frame how designed for bike parks, slope style, dirt jumping and gated racing should be addressed. This is what we've come up with… Black Market Bikes is proud to announce the the arrival of our prototype short travel frame….the “Killswitch”. We worked closely with Pablo Tafoya in developing our "Hammer-Link" design creating a our compact low profile suspension frame. The Hammer-Link provides 4 inches of rear wheel travel while maintaining a stiff, flickable feel with short 16” chainstays and the lowest seat height of any suspension frame….period. The Killswitch has the ability to be run single speed or geared for true versatility. Handmade from 6061 T6 aluminum with function and durability in mind, the Killswitch was meant for the bike park… this is not one of the usual suspects in fresh paint. Like anything we produce, there was a need for something more… and the time has come to… "throw the switch!!!"
