Precision CNC milled from a single piece of 7075 aluminium, the dual-plane cutouts maintain strength whilst reducing the chainring’s weight to a mere 78g. We’ve radially brushed the ring and had them deep anodized to give the industrial feel we strive for at F5… and the result is something we’re chuffed to say is made in China.

 

We’re pairing it with our pista track cranks. The arms are 170mm, 144BCD with a JIS taper. On a standard 68mm bottom bracket shell, a 103mm BB will give a 42mm chainline, 107mm for 44mm. The arms and chainring weigh ~650g.
