Blackburn EX-1 Disc Carrier The Blackburn EX-1 has been recognised as a fantastic rear rack for more than 30 years. This Disc version of the rack has been reconfigured to fit frames with disc brakes. Because it's mounted to the rear wheel's QR skewer this EX carrier fits frames lacking rack eyelets. Supplied with extra-long QR skewer to anchor the racks 'feet'. 3-strut design double-triangle construction for Forth Bridge-like structural integrity. Robust 12mm gauge aircraft-grade aluminium rod construction gives Blackburn the confidence to back this rack with a lifetime guarantee. Fits 26" and 700c frames. Compatible with Copilot child seats. Manufacturer's published weight: 535g. Manufacturer's published payload: 9kg per side.
