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 chain keeper in the garage. Always use a new chain with a new chainring.

The most advanced, Patent Pending narrow/wide tooth profile on the Market guarantee minimum of 12 months of excellent chain retention capabilities! We mean it. You can finally take your chain keeper off of the bike. Tested by XC Silver World Champion Marek Konwa. Used by World Champion - Maja Wloszczowska!
