X-SYNC 2 Oval - since day one, SRAM has been dedicated to providing riders with component options that fit their own individual riding style. It’s undeniable that some riders’ pedaling styles benefit from oval chainrings, so they’ve engineered the new X-SYNC 2 Oval chainrings to give them the advantage they want. They are the only oval option available with their genuine X-SYNC 2 teeth profile, so they are the only oval chainrings on the market that are 100-percent optimized for Eagle. More options. X-SYNC 2 Oval. Only from SRAM.
X-SYNC 2 Eagle is the next evolution of SRAM X-SYNC technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC EAGLE design reduces friction and the accumulation of mud, grit and grime.
