SRAM's Eagle rear derailleurs are optimized for cassettes with a spread of 10 to 50 teeth. In order to continue to provide you with top-level switching performance with the extremely high bandwidth, KCNC has developed adjustable derailleur rollers for the upper position. These have three eccentric mount and enable mounting with an offset of 3 mm; 4mm or 5mm. With the offset and the selectable number of teeth (also available with 14 and 16 teeth) you can compensate for manufacturer-specific length differences on the derailleur hanger and thus continue to shift smoothly into the smallest and largest sprocket.
The light KCNC jockey wheels give your bike an individual look. Milled from high-quality aluminum and fitted with rust-free, sealed stainless steel bearings, they stand for a long service life. Slightly extended narrow-wide teeth guide the chain more reliably and make the derailleur rollers perfectly compatible with Eagle 1-speed drives.
The wheel is only compatible with rear derailleurs up to 50 teeth if a cassette with 52 teeth is to be installed.
