This 9 speed shifter makes good use of nylon composites in both top & bottom shells as well as in the lever. Box Three is Box's performance & value tier, so this shifter sheds all the fancy trappings of the top 2 tiers but still maintains their incredible shifting characteristics. All Prime 9 shifters take advantage of the 9 speed's inherent durability, simplicity, & reliability.
