Resurface your MTB Rotors On Trail Videonate collins
Resurface your MTB rotors on trail video – BikeCo Tips in Sixty.
Whether from heat saturation or contamination occasionally riders will need to resurface rotors.
Signs that your rotors need to be resurface include being visibly darker, less total power, as well as noise under use as they heat up. Heat noise is typically a screech or squeak, opposed to contamination noise which generally sounds more like a goose honking.
What You Need
This is a simple task and a quick fix on trail.
You need a water bottle and a source of dirt without much organic material.
Organic material may have oils which will contaminate the rotors creating issues. In Southern California we tend to have sections of dirt without too much organic buildup. If you’re riding in pure loam dirt you may have additional issues with this…
What You Do
First create a small mud pit.
Dab your fingers into the mud pit. The grit of the dirt becomes like the grit on sandpaper. Rub your fingers around the rotor a couple times to resurface it.
Before you drop into that steep chute pedal a couple circles and snap the brakes. There will be more noise compared to resurfacing rotors in your garage – but this is an effective means to quiet a squealing rotor and provide more power during your ride. Obviously you should ensure proper brake function and power before riding!
Riders constantly burning rotors may find the additional heat capacity of larger rotors a good option. Four piston brakes are another option for riders who want more power.
