Fix it, don't replace it.

You don't know how your rotor bent. It could of been the brutally bouncy shuttle ride up the side of a mountain, or maybe it was that twenty-yard cartwheel your bike enjoyed into the forest. What ever the case, accurately straighten it with the Park Tool DT-3 Rotor Truing Gauge.

Note: The DT-3 is designed to be used while wheel is mounted in a Park Tool TS-2.2 or TS-2 Professional Wheel Truing Stand.

Easy fix for expensive rotors

  • Familiarity: I've used it once or twice and have initial impressions

This tool makes it easy to true your rotors and make them new again.
