SRAM's PG-1130 cassettes are affordable versions of their 11-speed cassette range. These cassettes are optimized for off-road and feature PowerGlide II shift technology for smooth and positive shift performance with minimal additional weight.
Bottom bracket standards seem to be a dime a dozen these days, so to stay on top of the game, SRAM stays current to reflect the sizes used in the industry with the GXP BB92 Bottom Bracket.
The strongest system is a chain with no weak links. Eagle chain links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear.
It might look normal from the outside, but the engineering inside this incredible chain design makes possible a gear range previously found only in 2-chainring drivetrains.
The XX1 chain represents the latest breakthrough in a long line of precise, light weight chains from SRAM. Its designed to deliver the greatest strength.
