Factory Jackson review: http://factoryjackson.com/2015/04/07/renthal-1xr-retainer-chainring-review/

“Although it has been a while coming, Renthal’s entrance to the narrow/wide retaining chain ring market is damned impressive. It’s nice when companies take a step back to make a genuinely great product and now another great British company have cracked it again. Must be something in the water.”
“The Renthal 1XR chain ring is an absolute no brainer. Highly recommended.”

“During an excessively muddy and snowy winter on the East Coast my Renthal ring saw plenty of thick muck and it never failed. Not once”.
“Renthal has created a winner with its 1XR ring: it has been working flawlessly”.
