                    Great value Deore 2-piece design chainset for 9-speed transmissions. 
                     
                    • The 2-piece design chainset features an external bottom 
                    bracket system which is a lightweight rigid design that is 
                    incredibly strong and durable. 
                     
                    • Lightweight and rigid steel bottom bracket axle 
                    SG-X chainring with patented spike pins give smooth and fast 
                    gear shifts under load. 
                     
                    • Lightweight aluminium outer with steel middle and 
                    inner chainrings. 
                     
                    • We recommend that the bottom bracket is initially 
                    installed by a bike shop to ensure perfect facing and fit.
