Strummer HR-360 Ratchet Gen-2 Centerlock Hub
Strummer HR-360 Gen-2 is designed as one of the best hubs for road disc and gravel bikes. Made for high speed on smooth roads, yet strong enough to handle uneven gravel surfaces.
Using the latest Ratchet 54T mechanism, this hub offers faster response and better performance compared to the previous generation. With 6.7° degrees of engagement, power from the pedals can be efficiently transferred to the wheelset for optimal acceleration.
This mechanism can also be upgraded to Star Ratchet 60T, resulting in closer engagement with 6° degrees of engagement, providing very quick response especially when starting to pedal from a stop position.
