For 2012 SRAM is offering additional 2X10 gear options for XC, trail or all-mountain riding in its X0, X9, X7 and new X5 families — 36-22, 38-24, 39-26 and 42-28
• The 38-24 chainrings are designed for the 29er market, providing easier gearing for steep climbs.
• The 36-22 chainrings offer the lowest 2X10 gear available from any system.
• The 39-26 and the 42-28 chainrings continue to be the most versatile offerings for XC and short-travel bikes.
New to these drivetrain offerings are dedicated 38t and 36t front derailleurs available in our X0 and X7 families. The 36-22 and 38-24 chainrings are available with an all-mountain guard option. Price for spider/bolts/rings/guard range from $130-$145
