If you have ever thought about running 1x9/10/11/12 speed and wondered how to solve chain retention, this is an answer. Its specially designed wide-narrow tooth profile keeps the chain really snug, allowing you to leave your chainkeeper in the garage. Always use a new chain with a new chainring.
The most advanced, Patent Pending narrow/wide tooth profile on the market guarantees a minimum 12 months of excellent chain retention capabilities! We mean it. Tested by XC Silver World Champion Marek Konwa. Used by World Champion - Maja Wloszczowska!
For for very aggressive enduro riding it is still recommended to use an upper chain guide or at minimum a bashguard.
