There is a wide choice of spiders to fit pretty much any type of chainring on the market. Uno and Duo users will find their spiders incorporated into the chainrings. Designed with the performance XC racer in mind, Duo rings are intended to be used in pairs, instead of the normal triple-chainring setup.
The inner ring attaches to either RS-7 or RS-8 cranks using our exclusive Sweet Torque™ interface and acts as the 3-arm spider for the outer ring, saving weight.
All Duo outer chainrings utilise our slickshift technology, meaning that it is possible to run a 27T - 44T setup, maintaining a similar gearing range to a standard 3-ring chainset. Quite simply, it is perfect for all but the most severe terrain and offers a substantial weight saving.
