I recently placed an order on Share the Road for a couple of decals which I received in a timely manner. If you are pro cycling road safety you might want to check out Share the Road offerings. They have decals, jerseys and t-shirts all with a road safety message.
I only purchased a couple of decals this time around as the jerseys are more targeted at markets where measurement is in imperial, but they do have some cool decals for the car, bike etc and also t-shirts which are worth a look.
The two stickers I got are:
One has gone on the car and one is being kept for my future velomobile. They are a very good quality decal so hopefully will last some time on the car and/or velomobile. The stickers cost me US$4.50 each delivered to Australia. What would be bool but is to have a “decal wrap” for the Sinner Mango Sports that makes the point that “you own a car, not the road, Share it.” That is a highly visible mobile billboard spreading the message. Something to think about for sure.
I did have one small difficulty in placing the order. It seems that their online shopping cart does not play nicely with international orders but if you email STR Apparel with your order details and shipping address they will send you an PayPal invoice so you can pay for the order securely with PayPal.
