Using this on a cargo e-bike to go to 220mm disc on front (stock was 180, had increased to 202mm but wanted more stopping power) front forks are pretty substantial so you will want to check to make sure you are comfortable going with such a big disc/or check with manufacturer) but the adapter works really well.
