ユニバーサルディスクブレーキアダプター｜140／160mm・Shimano／SRAM対応・軽量

Front adapter is fine. The rear adapter is built too late and cracks easily at the middle bolt hole. The base of the rear adapter is also too small so it digs into the frame and sits crooked. I have used these on four different bikes. Two are broken and aligning is difficult on all four.

This is for the rear adaptor. Front works fine. The rear adapter is built to light and is prone to cracking. The base of the adapter is also too small which makes alignment very difficult.

Simple, lightweight, and does the job well. The adapter fits securely, installation was easy, and the Shimano/SRAM compatibility makes it a very practical choice. Great option if you want a reliable brake adapter without adding unnecessary weight.
