E.g. if you have 180mm post mount on your fork and you want to run a 203mm rotor then you should get a 180mm-203mm adapter. \u003c\/span\u003e\u003cspan\u003eA different scenario is if you already have an adapter on your frame. E.g. if you have a 180mm rotor with an existing 160mm-180mm adapter purchase a 160mm-203mm adapter to replace your existing adapter. \u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cp\u003eThere is a little bit of variation in actual caliper, rotor and mount designs so in some cases the washer included may need to sit between the mount and adapter to get the correct spacing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThese adapters will not work with flatmount brakes on road\/gravel bikes.\u003c\/li\u003e\n\u003cli\u003eIf you want to be able to return the adapter you'll need to keep it in mint condition which is best achieved by nipping the bolts up very lightly to check that you're happy with radial alignment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAfter something for 200mm rotors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWe don’t sell anything for them, sorry.\u003c\/p\u003e\n\u003cp\u003eWhy? We think they’re a false economy.\u003c\/p\u003e\n\u003cp\u003eOnly SRAM offers supports 200mm rotors, and they’re quite expensive - at least $100 each. By installing a 200mm rotor you’re locked into replacing that with an expensive 200mm rotor each time it needs replacing. At Outspoken we're all about well-performing products at reasonable prices, and 200mm rotors simply don't pass the sniff test for us.\u003c\/p\u003e\n\u003cp\u003eIf you switch to a 203mm rotor, you can get comparable performance rotors for a fraction of the price, making future replacements much cheaper. As of 2 Feb 2026, it costs at least $120 for a SRAM centerline rotor and $60 for a 40P (160mm-200mm) SRAM adapter - a total of $180. From us, you can \u003ca href=\"https:\/\/outspokencycles.co.nz\/collections\/all\/products\/gpvn-disc-brake-rotor?variant=39839867732046\"\u003eget a fantastic 203mm rotor\u003c\/a\u003e ($33) and 180-203mm adapter ($15) for a total of $48. And that’s with our performance guarantee on the rotor.\u003c\/p\u003e\n\u003cp\u003eHowever, if you are set on 200mm rotors, you can buy official SRAM adapters (about $60 each).

Yes, it's two washers (aka rocket science). Place one over each bolt under the caliper to space it outwards. This will allow you to get that additional \"3mm\" (of diameter, not radius) to run standard-sized discs, instead of being locked into expensive sram rotors. Use it to space a 200mm setup to a 203mm rotor. Or use it in conjunction with an adapter, for example spacing a 200mm fork mount to a 220mm rotor. \u003c\/p\u003e\n\u003cp\u003eThe washers are stainless steel.
