Yeah, I mounted some Gatorskin sprinters up last week, and just rode them on rollers last night. They seemed either super slippery or super bouncy, can't really tell which, but the result was nearly crashing when doing rev outs, and a top speed of only ~175 rpm when usually I can hit 200. Anybody else experienced this? Not sure that this means they'll ride poorly on an actual track, it was just weird.
