The ultimate solution for Shimano and other 64/104BCD cranks. If you have ever thought about running 1x9/10/11 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. KMC chains strongly not recommended. Always use a new chain with a new chainring.
The most advanced tooth profile on the Market guarantee minimum 12 months of excellent chain retention capabilities! We mean it. You can finally take your chainkeeper off of the bike. Tested by XC Silver World Champion Marek Konwa. Used by World Champion - Maja Wloszczowska!
