The middle eight cogs of the SRAM Red XG1090 Cassette - 10 Speed are machined from a single block of high grade tool steel, making for an exceptionally stiff cassette that weighs even less than a titanium one.
Cut-outs on the rear cog reduce the weight and increase the stiffness even more.
Between each cog is a StealthRing elastomer, which reduces vibration and noise to help your drivetrain run silently.
This cassette is the result of years of design advances, and gives great shifting performance and longevity at an incredibly low weight.

All you’ll need to do when you receive the bike is straighten the handlebars and attach one of the pedals. This service is free, and included every time you buy a bike. Find out more.
