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.
Is 180mm rotor enough?
1. 180mm rotors offer greater stopping power than 160mm ones and are better for larger riders and harsh descents. 2. 160mm rotors are lighter, provide better modulation and work just fine for small riders and bikes that won’t be used for downhill.
Does the size of the rotor matter?
You can exchange brake pads, experimenting with different material compounds for feel and durability, but rotor size has a much more significant influence on absolute brake performance. … The more heat your brake rotors can absorb, the longer they’ll retain stopping power, without fading.
How do I choose rotors?
How to Select Brake Rotors
- Smooth rotors offer the quietest operation, lowest dust and longest pad life. …
- Drilled rotors offer slightly more bite and friction than slotted rotors. …
- Slotted & Drilled rotors offer a compromise, midway between the benefits of slotted rotors and drilled rotors.
How big are my rotors?
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.
Are bigger MTB rotors 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.
Which MTB brake rotors are best?
The best mountain bike disc brake rotors
- SRAM CenterLine. No-nonsense stoppers that compare well with higher-end competition. …
- Shimano Deore XT M8000. Icey cold rotors that are fast-stopping and reliable. …
- Hayes D-Series Rotor. …
- Hope Floating Disc. …
- SwissStop Catalyst. …
- Galfer Wave. …
- TRP-25. …
- Magura Storm SL.
Are front rotors bigger than rear?
Front rotors are larger because the front brakes do most of the work. Using rotors the same size on the rear would waste gas (more weight) and make the car handle worse (extra unsprung weight) and accelerate slower (more rotating mass.)
Do I need 160mm rotors?
Sram’s road product manager, Brad Menna, agrees: ‘We recommend 160mm for road applications. That’s what provides the most power and best system performance for the widest range of riders and uses. ‘ Shimano’s Ben Hillsdon also agrees, and explains why 160mm rotors might be better able to cope in certain situations.
How long do MTB rotors last?
A bike’s disc rotor can last for an average of 2 years for a rider who rides 3-5 times in a week. . Generally, it is advisable to install a new set of brake pads whenever you replace the disc rotors.
Will 203mm rotors fit 200mm?
The adapters for 200mm rotors will work with 203mm rotors(mine do) as the rotor is only 1.5mm bigger in radius.
Do bigger rotors make a difference?
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.
Are thicker rotors better?
Increasing The Size Of Your Rotors Improves Heat Dissipation
The biggest benefit of increasing the size of your rotors is improved heat dissipation. When you use your brake rotors and pads hard (for example, at the track), they heat up faster. As a result, these parts will have a hard time cooling down.
When should I replace my MTB rotors?
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.
