- Hub technology
- Kronos hubs have earned their legendary reputation for quality and performance. There are multiple features that make this product a
winner: The Ratchet System® driver mechanism is extremely durable, reliable and can be serviced without special tools in minutes,
thanks to its simple press fit assembly. The press fit assembly also allows all hubs to work in almost any currently existing
axle configuration, making them compatible with almost every bike. The contact free seals and high precision build guarantee
smooth bearings; every bit of the rider’s energy is transformed into forward momentum. These features and the super
lightweight design of all the hub parts highlights the racing legacy of this classic hub.
