X-SYNC
X-SYNC 1x chainrings from SRAM ensure maximum performance and durability. SRAM's long X-SYNC tooth edges grip the chain earlier than traditional triangular teeth. The sharp and narrow tooth profile as well as the rounded slanted edges support the chain guide. To offer the best possible performance even in muddy terrain, the X-SYNC chainrings have recesses for the inner chain links and rollers to remove dirt and mud. Made in Germany, X-SYNC chainrings are a key component of SRAM's 1x drivetrain.

eTap
Wireless shifting, battery energy management and mechatronics - the RED eTAP technology serves one goal: to offer you the most intuitive operation possible. They call the shifting logic behind it eTAP. The right lever shifts into the higher gear, the left lever into the lower gear. You can control the chainrings via both levers. Simple, smooth and intuitive.
