Two important words to cyclists. We're all pretty hard core here. We have all been frustrated with cycling items that didn't hold up under the demands of regular use, in foul conditions, with grime and grease, and in the cold or heat. Everything must be built to withstand rigorous use, use with one hand while riding, and exposure to sunlight and water. Salt and chemicals in the winter, too.

Keep this in mind as you develop prototypes. Test, test, test...

I don't speak for everyone, I understand, but few of us really care how something looks. We care that something works and will keep working.

Good luck,
Phil G.
