SRAM XX1 X-Sync Chainring

SRAM XX1 Chainring

SRAM’s new XX1 drivetrain is packed with the latest technology in order to bring your riding to new heights. The new XX1 group has been designed to be run as a 1x11 drivetrain and will provide lightning fast shifts and flawless chain management. Each tooth on the chainring has been precisely machined to integrate with both the inner and outer links of the chain perfectly. The X-SYNC™ fits the single-ring universal spider allowing to change the chainrings without having to remove the carbon crank arm.

A full range of chainring sizes in 2-tooth steps are available, giving you the freedom to tune your gearing to your riding style. For standard use, a 32T chainring is recommended. Adjust with larger teeth for more top-end speed and less climbing gear, or go smaller for a lower climbing gear with less top end.

  • Compatible with the SRAM 1x11 Carbon Crankset
  • Aluminum
  • 76mm BCD
  • 4 Bolt

Awesome!
The new XX1 drivetrain is so awesome. The chain retention is unbelievable, which was the reason I chose to use it for my 1x10 setup.

great chainring
The design of the teeth really make this chainring resistant to dropping the chain. Easy to install without removing the crankarm. On the XX1 setup the ability to change allows for finetuning the bike for individual courses. The derailleur can handle 2 tooth changes up or down on the chainring without having to alter the chain length. Besides being a bit pricey it is hard to find anything not to like.

No more chain drops
The wide/narrow tooth design has not dropped the chain to date. Easy to install without removing the crankarm. There are enough options in tooth count to tackle any rolling terrain. I'd recommend having at lest 2 sizes on hand and keep one in your bike bag. The derailleur can accommodate 2 tooth changes up or down on the chainring without having to alter the chain length. Although a bit pricey compared to other 1x narrow/wide rings on the market, it is hard to find anything not to like. REMEMBER that SRAM XX1 chainring BCD is proprietary to SRAM XX1 only. Will not fit other crankarms.

Sram Does It Again!
My 15 year old daughter uses this chain ring for high school league competitive mountain biking. She is very pleased with the gear ratio that it provides but the best part is she has never dropped her chain!

As always another top quality product by sram. I recently purchased a new set of xx1 cranks but needed a chan ring, was a bit pricey but well worth the price. I was very pleased once it was installed

A very good upgrade
I bought from a friend a XX1 crankarms and no chainring, so I installed a Race Face 32t on it. Then 6 months later start to hear noises everytime I put pressure to go uphill. So I decided to go for the XX1 Chainring and put a 30t to lightening my uphill ride. As a result, no weird noises and an extra improvement to climb better.
