Excellent quality and functionality.
Easy to maintain as with all the linkage on a Deviate bike having their own individual grease ports which is just genius for the longevity of bearings during wet,muddy or dry dusty conditions.
All bearings are also protected by double rubber seals to stop any ingress of the elements.
The large jockey wheel is silent when peddling and does not add any more resistance to a day's ride than a normal system.
Yup,Deviate has you covered,all you got to think about is just ride.
