Which is better 160mm or 180mm rotor?
1. 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.
Is 180mm rotor enough?
They do a better job of displacing heat generated from braking, and can provide better modulation. In general, a 180mm front and 160mm rear rotor will provide you with ample braking power for a 29er hardtail.
Are front and rear rotors the same size?
Originally Answered: Are front and rear rotors the same size? Usually not. On most passenger vehicles the front brake rotors are larger, with a larger friction surface. This is because when the brakes are applied, the weight shifts forward, the front end drops and the rear end raises.
Do bigger MTB rotors stop better?
The larger rotors not only provide more power but they also put less strain on your forearms and shoulders since you don’t need to pull the brakes as hard, keeping you fresher for longer and allowing you to ride more actively.
Why are my front rotors so big?
The larger rotors not only provide more power but they also put less strain on your forearms and shoulders since you don’t need to pull the brakes as hard, keeping you fresher for longer and allowing you to ride more actively. If you hit the front brakes with a 220 mm rotor, the wheel will lock up relatively quickly.
Can rear rotors go on front?
For the majority of vehicles with disc brakes at all four wheels, there is no specific designation on which side a rotor must be placed. The rotor that fits the left front will typically fit the right front as well as both sides of the rear axel. There are exceptions of course.
What rotor size do 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 larger rotors increase stopping power?
A larger rotor provides more metal to absorb the heat and a greater surface area to dissipate it. Hence they can sustain higher braking power for longer. So, yes, larger rotors do provide more braking power.
Do I need 203 rotors?
If you’re racing enduro just go with the 203mm rotors. The weight difference is negligible but the stopping power is much better.
Can you mix and match rotors?
Should be no issue to mix and match. You may want to clean the previously used rotors first-a light sanding/scuffing and a wipe down with iso alcohol should do it.
