In addition to DEORE and XT mechanical drivetrain components, pedals, and more, we can add 2.2mm thick disc brake rotors to this weeks growing list of Shimano product announcements. With an increase in thickness to 2.2mm, Shimano says its new rotors are engineered to improve braking performance, control, and durability for todays downhill, freeride, enduro, and e-MTB riders. Additionally, Shimano is making an intentional shift from its 203mm size to 200mm to simplify setup and frame/fork fitment.Shimano says the 2.2mm thickness and new vent hole construction improve durability, consistency, and control.Thicker is BetterAs we learned when SRAM introduced its HS2 rotors a few years back, increasing the thickness of the brake rotor can noticeably impact braking power and performance. With the introduction of these new 2.2mm thick rotors, it seems Shimano is finally getting on board the thicker-is-better train. They say they are intended to stand confidently on their own as a premium braking upgrade.Bumping up from the 1.75mm thickness of the standard versions, Shimano says the 2.2mm rotors raise the bar on braking performance for gravity-oriented riders and heavyweight e-MTBs. But Shimano claims it isnt only about more power; the added thickness also increases durability and impact resistance. Additionally, they state the new vent hole construction improves consistency and maintains predictable modulation, resulting in less hand fatigue.The 2.2mm thick rotors come in 200mm and 220mm sizes.SizesShimano has been making disc brake rotors in a 203mm diameter for many years. This size has always been a little confusing, given the even 20mm jumps between rotor sizes in the rest of the Shimano rotor lineup. And if youve ever run Shimano brakes with a 203mm rotor, then youre aware that it required the use of specific shims and/or adapters to do so.With the new 2.2mm thick rotors, Shimano tells us that its intentionally ditching the 203mm diameter in favor of 200mm. As Shimano puts it, this shift simplifies brake setup and alignment, reducing the need for extra shims or adapters for a cleaner caliper interface and broader frame and fork compatibility. In addition to 200mm, the 2.2mm rotors are also available in a 220mm diameter.CompatibilityThe new 2.2mm thick rotors are available in 6-bolt and center-lock interfaces, so they should work with virtually every mountain bike hub out there. Shimano says the thick rotors are compatible with its latest 4-piston braking systems, including XTR, DEORE XT, and the recently updated DEORE brakes.2.2mm thickness for great control and braking consistencyIncreased durability and resistance to bending in aggressive riding conditionsAvailable in 200mm and 220mm sizesAvailable in 6-bolt (RT-6B750) and CENTER LOCK (RT-CL750)Compatible with SHIMANO XTR, DEORE XT, and DEORE 4-piston brakesShimano 2.2mm Thick Brake Rotors: Pricing200mm, 6-Bolt: $60 USD / 49.99220mm, 6-Bolt: $75 USD / 54.99200mm, Center Lock: $70 USD / 49.99220mm, Center Lock: $80 USD / 54.99For more information or to find a dealer near you, head to the Shimano website.bike.shimano.comThe post Shimano Introduces New 2.2mm Thick Brake Rotors for Improved Braking Performance appeared first on Bikerumor.
