Please note: unfortunately the Swift track frame has now been discontinued.

The infamous Swift track frame is back – featuring double oversize tig welded tubing and an aggressive track geometry. Updates for the 2018 version include a 44mm headtube and tapered carbon forks. All this creates a fast and responsive ride making the Swift an effective race frame for the street, track or crit.

We first released the Swift back in 2013. In this time it’s developed into one of the go-to steel fixed gear/track frames that’s been tried and tested in crit races, alleycats and on the track all around the world.
