So what is the Carmichael derailleur? It is a Joe’s derailleur without the small Joe’s sticker on the p-knuckle. That is, genuinely, the only difference.

Ingenuity Sports of Altadena, California bought the design (and possibly the Joe’s brand) and either wholly or partially rebranded it as a Carmichael product. It's possible that Ingenuity Sports ran both brands in parallel.

it is also noteworthy that all Joe’s, Rhino and Carmichael were fitted with Carmichael sealed bearing pulley wheels.
