Are 160mm rotors good?

180mm rotors offer greater stopping power than 160mm ones and are better for larger riders and harsh descents. 160mm rotors are lighter, provide better modulation and work just fine for small riders and bikes that won’t be used for downhill.

How many mm should brake rotors be?

How many mm should brake rotors be? The standard solid rotor is 12mm (0.472 inches) thick. It should not be ground to less than 10.5mm (0.413 inches). The standard vented rotor is 20mm (0.787 inches) thick and should be ground to no less than 18.5mm (0.728 inches).

How do I know what size rotor I need?

Call your local OEM dealer and ask for the original rotor sizes or OEM rotor/pads part numbers based on your vehicle’s VIN number (VIN# is referenced in your ownership papers). The dealership may not tell you the rotor size, but they will give you the genuine part numbers for your vehicle.

Do bigger disc rotors stop better?

Simply put a bigger rotor provided better braking, and a four pot caliper provides better braking – better meaning more, and more control (Everything else being equal). For the same force between the disc and pads, a bigger rotor generates more torque on the wheel – i.e. more stopping force.

Is 140mm rotor enough?

‘In my opinion a pair of 140mm rotors look nicest, but as many riders are over 80kg there is a chance braking performance can be affected in certain conditions,’ says Giacomo Sartore, groupset product manager at Campagnolo. ‘This is why we recommend either a pair of 160mm rotors or 160mm front, 140mm rear.

What does mm mean on rotors?

You’ll need to know the minimum thickness. The rotor’s minimum thickness tells you the minimum operational level of your rotor. This level can be found engraved on the sides of the rotor, within the veins of the rotor, or on the hat of the rotor.

How far can you drive with 1 mm brake?

11mm is the starting point for the brake pads. You have used 7mm in 33k miles because you have 4mm left. It will take 33/7 or 5K miles to wear another 1mm.

Are thicker brake rotors better?

Thicker fins allows the manufacturer to produce a less expensive rotor because the surface that does all the stopping, the machined surfaces, can be made thinner but the replacement will still have the same discard thickness as the OE rotor even though the life expectancy can be severely shortened.

What do bigger rotors stop better?

The bigger rotor will be better for both dissipation and storage of heat. So heat dissipation and storage provide more braking power. The lever arm provides greater braking torque because of the longer lever arm. End result bigger rotor equals more braking torque and more braking power.

Can I use any rotor with disc brakes?

You can use any rotor you like with any brake, within reason. Some rotors have narrower brake tracks than others, i.e. Shimano, but generally, it’s just a metal disk.
