The DT SWiss 370 front quick release hub was chosen for the HSB Rhythm RDF mountain bike as it is a strong, lightweight hub that easily accomodates the the 185mm rotor. Additionally, we chose this hub to have harmony and compatibility with other parts on the bike. This attention to details... from colour co-ordinating parts to equipping the bike with different components from the same manufacturer give the HSB Rhythm a clean, matching, professional and "finished" look.
