After searching 305 results from a search for some options of 20 hole hubs I'm left with asking, so sorry if I missed a thread.
Anyway the freehub on my DA7850 composite wheel has given up, 13 months after buying them

Shimano have said a replacement will be at least 6 weeks, also I had 2 spoke let go, these are dated as 8 weeks before any arrive in the UK so I've decided to throw the hub away and the spokes and just get them rebuilt rather than wait for ages only to have wheels that I will wonder if they will fail again, forget the fact that I was quoted £4 ($6) per spoke and in the region of £130 ($200) for the freehub.
So any suggestions, recommendation? I use these wheels for wet races and also training so ideally the hub should be serviceable and although light suitable for a hard life.
