Middleburn RS7 Duo was designed with the performance XC racer in mind, we were the first company to use a two ring set up for mountain bikes in 1995.
The inner ring/spider attaches to 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 29T – 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.
MATERIAL: 7075 T6 alloy
RATIO: 27, 29, 32
CHAINLINE: 47.5mm using a 113mm bottom bracket
FINISH: Hardcoat (grey)
