When I first was interested in a seasucker rack there was some concern of them not working in Cold Weather. well the do! Just make sure that your Vacuum cups a warm when you put them on, and they will hold all day!
I took my Singular Gryphon to Potato Creek to ride in the snow, it was 28 degrees and at least 3 inches of snow on the trail, sun was out and it was a great trail ride!
