> The wide pivot link design boosts strength and rigidity. Flex is suppressed, creating sharp, precise shifts that are faster and smoother, even from low to high gears off of the saddle.

Features

• > Wide link design : 20% increased rigidity.
• > Pivot locations for less cage deflection : Pivot location at cage was moved to the point of maximum force to reduce cage deflection.
• > Narrower chain cage : Narrower chain cage to accommodate 10-speed chain.
• > Hyperdrive compatible
• > Light action spring
• > DUAL SIS front index shifting
• > Specially-designed for 10-speed
• > Capacity : FD-5600 16T, FD-5603 20T (specially-designed for FC-5603)
