Shimano 10 Speed Dura Ace 7900 Bar End Shifters, with cables, are precision-engineered for reliability and durability. They easily fit into bar ends and secure firmly for assured shifting. Thes elevers are compatible with 10-speed drivetrains and can be used with double or triple chainsets but are indexed system compatible for a crisp rear change. They come complete with SP41 gear cables, which are lubricated internally along their length with low-friction silicon grease to reduce cable friction
