If used on the front with a 203mm rotor obviously in most cases you have to add the 3mm. If the rotor was 200mm you would not need too. I used the small washers from caliper brake pads... Upgraded 160mm ebike rear brake to 180mm. No issues with this adapter worked fine.The larger rotor hit my kickstand mount because it mounted behind the frame bracket.I moved it to the front of the bracket but it puts more stress on the kickstand mounting flange. ### ⭐⭐⭐⭐⭐ Works as 160 to 180 adapter *by L***E on Reviewed in the United States on 3 September 2024* I bought this to go from a 160mm to 180mm IS / post mount adapter for the rear of my 2016 DB Hook. It worked perfectly without spacers! Tested it on over 20 miles of single track and it held up. ### ⭐⭐⭐⭐⭐ Worked for what I needed *by D***G on Reviewed in the United States on 8 May 2024* Straigt forward install I took off my old adapter that broke and bolted this one up it worked perfectly with my Hayes A4 Caliper and my 180mm rotor. Only thing I would suggest is to put thread locker on the included screws but other than that 5/5 ## Frequently Bought Together - JooFn Disc Brake Caliper Mount Adapter IS Front 203mm Rear 180mm - Teyssor 140mm 160mm 180mm 203mm Bike Disc Brake Rotor with 6 Bolts Fit for Road Bike Mountain Bike BMX MTB - JooFn Disc Brake Caliper Mount Adapter is to PM for Front 180mm Rear 160mm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/327703805-disc-brake-caliper-mount-adapter-is-front-203mm-rear-180mm](https://www.desertcart.kg/products/327703805-disc-brake-caliper-mount-adapter-is-front-203mm-rear-180mm) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-26*
