Shimano (and others) have long maintained a 203mm diameter disc brake rotor. SRAM (and others) liked the round numbers of a 200mm rotor. Shimano\u2019s 203mm was a nice round number, eight inches, before disc rotors moved to metric sizing.<\/p>\n<p><a href=\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/06\/L1013141.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-143064\" src=\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/06\/L1013141.jpg\" alt=\"\" width=\"1200\" height=\"800\"  \/><\/a><\/p>\n<p>Now, Shimano is making its disc rotors 200mm. A tiny change that does away with an annoying standard discrepancy. It was one of the easier ones to fix, as you only needed tiny washers to make a caliper designed for 200mm rotors work with a 203mm rotor. But still, progress is progress. Let\u2019s celebrate.<\/p>\n<p><a href=\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/06\/RT-CL750_220_3.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-143069\" src=\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/06\/RT-CL750_220_3.jpg\" alt=\"\" width=\"1200\" height=\"1200\"  \/><\/a><\/p>\n<p>Thicker rotors debut new-to-Shimano diameter<\/p>\n<p>The bigger change to Shimano\u2019s rotor is their thickness. Rotors beef up from 1.75mm to a full 2.2mm thickness. \u00a0Why? To significantly improve durability for more aggressive riding and for eMTB use. The thicker rotors are supposed to give more control, as there\u2019s less temperature variation. They\u2019ll also be more durable and more impact-resistant since they are beefier.<\/p>\n<p>This change applies to the 200mm and 220mm version of the Centerlock (RT-CL750) and six-bolt version of Shimano\u2019s CL750 rotor. It is compatible with all current generation four-piston brake calipers, from Deore to XTR.<\/p>\n","protected":false},"excerpt":{"rendered":"Shims be gone!
