Misaligned dropouts bend axles and skewers and cause tracking and shifting problems. This pair of gauges shows whether the dropouts are parallel, and gives you the leverage to correct a steel frame.

Highlights

• Checks front and rear dropouts are aligned and parallel
• Long handles and comfortable grips for leverage
• Spacers set for front or rear fork width
• Super B Premium range

How it works

Fit a gauge in each dropout and turn the outer bushings to the centre. If the male and female ends meet evenly the dropouts are aligned; a gap or mismatch means they need correcting.

In the box

4 handles, 2 bodies, 2 spacers, 2 inner bushings and 2 outer bushings.

Compatibility & fit

Steel frames can be measured and aligned. Aluminium and carbon frames can be measured but not aligned. Super B advises against using it on suspension forks, super-lightweight frames and oversized frames, and says to check with the frame maker before aligning. Prefer to leave it to us? Our workshop can check and align dropouts.
