    The RST used in the GGA SL is a game-changer. I have bike-pack-adventured over the last 18 months exclusively on these. The ride quality is excellent on the road, AND can handle big hits off the road. The performance has been impeccable considering my full-gear set-up(weighing over 50lbs total: sleeping bag, sleeping pad, cookware, spare clothes, rain gear, tools, food…..), conquering the harsh routes on the infamous Hot Springs outside of Boise, Idaho, which at times feels more like a full-blown mountain bike adventure. These wheels definitely help me take the gravel bike places they typically can’t handle. What I love about these wheels is how smooth they feel over super chunky gravel off-roads. As amazingly light as they are, they roll excellent with 42mm tires and make 12-hour days in the saddle as good as it gets.
