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.
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.
Brake pad compound is important when it comes to the performance of brakes. The two most common brake pad types are resin and metal. Resin pads add more modulation and noise control over metal brake pads and metal pads offer more power and fade resistance
