Finger Shift Lever Ratchet Ring for your left, or front derailleur side shift lever. New "QS" part--for best results, pair with "QS" front derailleur. 

When installing a new ring the raised number must face AWAY from your handlebars so the teeth will properly engage the finger shift lever. We recommend replacing this part every 35,000 to 40,000 miles.
