What size rotor Do I need MTB?

For aggressive enduro riders with large 29” wheels, 200 mm rotors are mandatory and upgrading to 220 mm rotors is worthwhile for heavier riders. Trail bikes also benefit from powerful brakes. Unless you’ve got powerful brakes such as SRAM CODEs or a four-piston Shimano model, we would always resort to 200 mm rotors.

Do bigger rotors stop better MTB?

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.

Do brake rotors matter MTB?

Fitting a bigger rotor will not only give you increased power, reduce arm pump, but also improve modulation and heat management as the rotor will heat up slower and cool faster over the larger radius.

When should I replace my MTB rotor?

Braking erodes material off the rotor depending on the riding conditions, rotors will typically last through two or more sets of brake pads. When a SHIMANO rotor measures 1.5mm thick or less, it’s time to replace it. A new rotor should always be accompanied by new brake pads.

What is the lightest MTB rotor?

AbsoluteBlack has introduced what they claim is the lightest CenterLock rotor in the world. The Raven SL uses FEA analysis, extensive heat treatment and a two-piece design to tip the scales at just 95g for a 160mm rotor. By comparison, Shimano’s IceTech XTR’s 160 comes in at a claimed 160g.

Are front rotors the same as back rotors?

Larger Brake Rotors: Today, front brake rotors are designed to be larger in diameter than the ones located at the rear of a car. This is done in order to provide more stopping torque when the brakes are applied. Thicker Brake Rotors: Modern front brake rotors are also designed to be much thicker than the rear rotors.

How long do MTB brake rotors last?

But as a result of these physical demands, it is a good idea to check them for wear regularly. Disc brake rotors will typically last through 2, maybe 3 pairs of brake pads (pad material and riding conditions influences this), but it’s never a bad idea to add a thickness check to any regular maintenance schedule.

How do I know what size rotor I need?

How to check your rotor size:

Start by checking the vendor’s catalog fitment notes.
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).

Are Floating Rotors better?

The floating multiple-piece rotors have a few advantages over their single-piece counterpart. First, they are lighter than rotors of the same size. The center is made out of aluminum which lightens up the total weight of the rotor. They dissipate heat better and run cooler which will help to prevent brake fade.

Do rotors go on the front or back?

The rotors are the circular discs that are connected to each wheel (two in the front and two in the back). Rotors are designed to turn motion (kinetic energy) into thermal energy (heat).

How big are the brake rotors on a mountain bike?

What to know when buying new mountain bike disc brake rotors 1. Size. Rotors come in 140mm, 160mm 180mm and 203mm sizes, and depending on the category of bike you’re riding, it will be set up for a different size disc — the front rotor will usually be a size up from the rear.

Why are floating rotors used on mountain bikes?

Floating rotors sees the steel disc mounted to an aluminium carrier, a technology borrowed from motorbikes. Floating rotors are claimed to offer better heat dissipation and improved warping resistance, but the real benefit is they are always lighter than non-floating designs.

Where are disc brake rotors made in the UK?

The aluminum carrier is CNC machined and riveted to a laser-cut steel disc; everything is made in Hope’s Barnoldswick, UK facility. With a two-piece design, Hope says the Floating Disc rotor will resist warping under extreme heat and the perforated rotor does well to clear muck.

How big are the rotors on a SRAM disc?

Sizes: 140mm, 160mm, 180mm, 200mm, 220mm | Mount: Centre lock, Six-bolt | Price: $44/£30 | Weight: N/A SRAM’s CenterLine rotors aren’t a fancy two-piece design, and they can be a bit noisy; though not as bad as the gobble-gobble Avid discs of yesteryear.
