Designed to handle whatever you can throw at it. Polished aluminum crankarms in a wide range of lengths and the DUB bottom bracket system mean the Rival crankset will keep spinning, no matter what.

The new 10-52t, XG-1295 cassette gives riders more than ever before, with an unprecedented 520-percent range. For a little extra to avoid the hike-a-bike, a little more in the “spin to win” game, the XG-1295 cassette also allows bigger chainrings.

The SRAM battery is the power source for eTap® or AXS™ components. The same power unit is interchangeable between front and rear eTap® AXS™ derailleurs, Eagle AXS™ derailleurs, and the RockShox Reverb AXS™ seatpost.

The day in, day out Eagle ecosystem hero is now available with AXS. The GX AXS upgrade kit is your entry point into wireless drivetrain simplicity. Compatible with any of our Eagle ecosystem cassettes and crank arms

On any surface you can imagine, in any drivetrain configuration, the Rival eTap AXS rear derailleur will handle it. Secure chain management and fast, precise shifting make for a smooth and quiet ride, every time.

More than a mechanical derailleur with a battery and a motor bolted on, the Eagle AXS derailleur is the heart of the whole AXS system. It features a shorter cage for 10mm more ground clearance, with more chain wrap on the cassette.

SRAMs light, stiff, and durable direct mount chainrings let you pick the exact gearing you want and quickly swap sizes. X-SYNC technology keeps the chain where you need it to be, too.

True competitors are always looking for a performance advantage - a relentless pursuit of equipment that is lighter, stiffer, stronger and more durable. To create the best drivetrain possible, we re-examined and re-engineered our crankset design.

FULL PIN™ technology uses eleven lightweight, stamped steel cogs held together with 123 high-strength stainless steel pins. The result: a cassette that's light, durable and equipped with SRAM's super wide 10-42t gear range that's a perfect fit for any rid

FULL PIN™ technology uses ten lightweight, stamped steel cogs and one 42t aluminum cog held together with 123 high-strength stainless steel pins. The result: a cassette that's light, durable and equipped with SRAM's super wide 10-42t gear range.

The SRAM GX X-HORIZON™ rear derailleur is engineered for smooth, reliable shifting action-from the larger upper pulley offset to the 12-tooth X-SYNC™ pulley wheels. By eliminating unwanted chain movement, X-HORIZON™ shifts faster.

Whether for prized race machines or the build of their dreams, the XG-1299 cassette is the ultimate, giving riders unprecedented 520-percent range thanks to the new 10-52 tooth-span. Stronger racers are now free to choose larger chainrings.
