I have 2 pairs of their hubs built into wheels for my disc braked road commuter (1 pair were on the original wheelset as I later discovered & another pair I built myself) – 1 rear has had the freehub bearings replaced (by me – £3.50) after ~2500 miles in all weathers & the other pair are nearer 3500 miles of the same treatment with nary a grumble from anywhere, cheap / light(ish) / reliable – pick 3!
Depending on what model you’re after, sdeals had some in stock for not much cash last time I looked – failing that ebay usually turns up a bargain or 2 from far east suppliers, I got a pair of 711/712 for around £70 a year or so ago, around 400g for the pair.
