Which David Kirk frame is right for me?
There are two possible directions to take when having a Kirk frame built. The first is full custom which includes tubing selected specifically for you, paired with lugs or fillet brazed joints. This approach allows for a high level of customization. If you are interested in a road fixed gear or a sport bike set up for wide tires, rack or fenders then this is the way to go.
The other direction is the JK Series which consists of four models. The JK Series bikes are my highest performance offerings. These race bikes are constructed with a cost-is-no-object selection of the lightest and strongest main tubes on the market as well as chain stays and seat stays made exclusively for Kirk and the JK Series. This proprietary blend of tubes is silver brazed into lugs chosen specifically for the JK Series. These are made-to-measure race bikes, and are not available with fender or rack mounts.
