We’ve now had the chance to ride the bike in the Appalachians in NC for the better part of a year. The descents are not hugely long, rarely more than 1500 foot drop, but often steep(15-20% grade) and twisty.
We’ve experienced no brake fade or overheating issues. We do tend to descend fast, only breaking for corners, but for us, the RX4’s appear to be more than adequate.
