This is one of those things that used to be pretty standard on bikes that went away for a long time. It has been a side burner project around here for years. I have talked with CatEye, a few smaller makers and some third party importers from Japan. Take note, there are some pretty cool options in the fender mounted gadget scene over in Japan. It really came down to a numbers thing, the affordable options involved quantities too high for us, and the smaller runs could not be done a fair price to you.
Then Velo Orange went off and just got it done, and did a pretty darn good job.
It does everything a reflector is supposed to do, and looks good doing it. The time change is coming on fast, tail lights are a must for night riding, but a bit of extra passive reflectance never hurts.
We have added these to the store front and will do our best to keep them in stock.
