why would he need to send just the hub, when i sent my profile back, i sent it as a wheel, on a ground koxx rim, and they didnt say anything. when i rang up and explaind that there were bits missing out of the ratchet, they just said send it back with postage paid for when we post it back to you they didnt ask how old it was or if i had proof of purchase, and they did the rest for free, it only took 3 days aswell and the hub came back like new, cant remember exactley what they replaced, as it was so long ago but im pretty shure they replaced the ratchet, pawls, springs and the driver bearings, as they had gone and i got new bolts and washers lol. your best bet is to give profile a ring like bongo said, they will sort it out for you
