SRAM again raises the bar on rear derailleur performance with the Apex rear derailleur. The Apex WiFLi™ rear derailleur represents the same design philosophy that has delivered our best in class products for the road market. The SRAM Apex® WiFLi™ rear derailleur lengthens its cage and gets a slight variation in geometry to accommodate an 11-32 cassette. The range of gears is wider than the standard triple chainring system and saves a significant amount of weight. Features also include our precise Exact Actuation™ ratio that offers the widest range of adjustment coupled with a precise geometry to create market leading 10-speed performance.
WiFLi™ offers a wider gear range and is compatible with cassettes up to 32T
Exact Actuation™ means precise, even, gear changes throughout the shifting range
