Profile now offer their rear hub shell's separately. The hub shell is machined from 6061 aluminium and comes with the ratchet ring already installed; you can install these on your existing mini cassette hub as a cheap way of changing the colour and making it look fresh. 36h only.
Would this fit a madera hub? (SOURCE: Yes)
