A bicycle chain tensioner provides precise adjustment and alignment of a rear axle, and shields an adjusting screw. A tensioner housing includes an axle hole and a slide pressing against an axle flange, the slide positioned by the adjusting screw. The tensioner housing is moved forward and rearward by the adjusting screw to adjust the axle position. The tensioner holds the axle in the desired position while axle nuts are tightened to prevent the axle moving during tightening. An indicator on the slide points to a scale on the housing to match right and left tensioner positions.
