The Symetrics Marathon frame is the strongest marathon frame on the market. 
By not cutting out the sidewalls, the CNC machined 7000 aluminium keeps its complete strenght. Inside the frame, we have cut out as much as possible to make sure we have a super lightweight frame. By keeping internal bridges the frame walls are fully supported.
 
Every frame is CNC machined to perfection and pearl anodized for a perfect finish. The graphics are laser burned into the frame. Our frames are made in-house and are a product of The Netherlands.
