I had one for each of our bikes and ended up not using them because it was hard to get numbers to stick on the vented portion for more then a ride or 2. Besides by the time you put them on the venting is all but coverred. I did try painting numbers on one but again the paint just didn't last very well eitherdefo26 said:Im ordering A 1/2 vent cycra front number plate. I'm not expecting any improvements with cooler temperatures but I was wondering what size numbers to get for them. Im getting it because I think it looks sweet and my old one cracked.
