I saw this at Wall mart -Has anyone tried this.
It looks like a practicle, economical alternative to upgrade to STI on the Bars instead of the stem or DT on older 5,6&7speed Freewheel bikes. I have used Bar ends & kelly Take-offs in place of DT & Stems. Grip shifters are available in 6& 7 speed where as the other types are getting Rare. 6 & 7 speed Freewheels are also common
