Know before you buy
Yes, this chain ring is specifically engineered to be compatible with both 10-speed and 11-speed SRAM 1x drivetrain systems.
X-Sync technology uses a tall, square tooth profile that engages the chain earlier than traditional triangular teeth. This design significantly improves chain retention and reduces the likelihood of chain drops during aggressive off-road riding.
You should measure the distance between the centers of two adjacent bolt holes on your crank spider. If that distance is 76mm, this chain ring will fit your specific XX1-style crankset.
No, this chain ring is designed exclusively for 1x drivetrains. It lacks the necessary shift ramps and pins required to move a chain between multiple chain rings.
A 34T chain ring is a versatile middle-ground option. Whether it is suitable for your climbing depends on your rear cassette range and your personal fitness level, but it is generally considered a standard gear for most trail and cross-country applications.
