Throughout 2015 I have been involved in the development of a new street frame by Impurity Bike Co. The initial motivation behind this project was to create a frame that is: A) Robust enough for burly modern day street and ramp riding with; B) Sensible angles and geometry for nose manuals, regular manuals, grinds, airs and; C) To be visually appealing. As an Impurity rider I was granted the opportunity to influence the geometry of the frame as part of a team consultation process. I pushed for a 75.5 degree headtube angle because I wanted the frame to be reactive for nose manuals and G’turns – to give you a better idea of the rationale behind the 75.5 (HTA) I will tell you that the United ‘Mothership V.3′ is 75.25 (HTA) and the Impurity ‘Femur’ is 76 (HTA) – from personal experience I have ridden both the Mothership(s) and the Femur and I feel that a 75.5 HTA is a happy medium which is very responsive yet still has a sense of stability for ripping around and getting airborne, etc. Other aspects of the frames geometry worth
