Most stores have Candy1 for $49, and Candy1SE for $39.
but i can't find the difference.
the SE have a golden spring, just like the Candy2. The plain Candy1 has a silver one.
Candy 1 SE:
I think Candy 1 SE is a special edition where colors are changed from standard Candy 1 as you can see in the links provided. Candy 1 SE is not even listed at Crank Brothers website. So if you fancy a more exclusive color set and it's cheaper go for the SE!
They finally replied to my email i send before starting this question.
SE is simply the 1, from the last collection. They changed the names from SE, SL, etc... to 1, 2, 3, 11...
