Silverback Carbon road fork

Sirelli 2 is fitted with a Silverback Advanced Dynamics carbon fork. The carbon fork further reduces weight on the bike, improves steering precision and ride comfort. Finished in UD carbon, the fork has a tapered carbon steerer and the offset is tuned to suit the nature of the Sirelli.
