I am trying to find a convenient way to attach my race number to my bike. I saw (in an article on-line) a flat piece of rigid material (plastic) that could be mounted on the seat post or suspended from the front of the top tube using zip ties.

I suppose it could be made, but I was wondering if anyone has seen something like that that could be purchased. I am a member of Team in Traininig's St. Anthony's Tri team and thought that other team members would be interested as well. I would not mind making one or two, but 80 might be a bit much.

Thanks in advance and Happy Holidays
