Has anyone tried to mount a Niterider Digital Evolution on an '07 Specialized Sirrus? I was considering Switching my light set to my Sirrus from off of my Mountain bike, but I came across a problem. The mount for the lighthead is too small to clamp around the bars! Not only that but the cables for the rear dérailleur and brake extend right in front of the light. I'm beginning to think I need to get one of those mini front racks and go Dynohub with it..
