Install:
1.The part 1 into the indicator bracket corresponding end.
2.Sliding handle into the part 1 corresponding position lock good nut.
3.The part 3 into the corresponding position of part 4,set such as O-ring.

Instructions:
1.Install wheel in frame.Make sure rim is Correctly centered in frame.
2.Remove derailleur from derailleurHanger.
3.Thread inside shaft(Ref# 1)into derail-Leur mounting hoie.

7.After achieving correct horizontal alignment,keep indicator In same position and rotate to position B.lf
clearance.Between outer edge of rim and tip of indicator is lees than 4mm,rotate tool to position D.If clearance is greater than 4mm,Or if indicator presses against rim at position B or D,use Inner shaft and correction correction handle As a,lever to align hanger vertically.
8.With properly aligned hanger,tip of indicator should just contact Outer edge of rim at one position and have no more than 4mm Clearance at any of the other positions.Check and align all four Positions until is accomplished.
