The long awaited new collaboration between Kashimax and Nagasawa. The NK-1 saddle used a new softer cushioning, which is a welcome feature for street riders and track pros alike. Track Supermarket stocks this saddle in 5 finishes; White sofrina, black leather, black belseim (a synthetic Japanese fabric which is in between a suede and a felt), dark red belseim, blue belseim and brown belseim. The saddle shell starts life as a FG-4P NJS shell, and is cut to the new more modern shape. The cushioning is softer than the other Kashimax saddles. On one side of the front/nose of the saddle, KASHIMAX embroidery is featured, and on the rear of the saddle, the famous NAGASAWA logo is embroidered. This is a limited edition saddle. The rails are standard 43/44mm so this saddle will suit any regular seat post. Please note that the NK-1 Nagasawa saddle is a low stock item, and often can take time to custom order from Kashimax. This may add from between 10-16 days to your shipping time. Feel free to email us for stock status at any time.
