Hell of a saving if you're after some.
Needs a special hub doesn’t it?
What's the cheapest you can get the hub?
Think Strada had them for about £170.
I thought you could use any hub, as long as it had the tourque cap end caps?
£100 for the wheel from CRC. http://www.chainreactioncycles.com/dt-swiss-xr1501-spline-one-front-mtb-wheel-ps-/rp-prod174971 . As it happens I have one of these wheels in 29" size on its way to me that I won on ebay yesterday from the Wiggle outlet for £79.40 so would happily pass it on for the same price posted if anyone wants it as I changed my mind after winning and ordered the carbon Rise 60 wheel from CRC instead. I ordered some of these RS1's on Friday as been looking at them for quite a while but the cheapest I had seen was around £500. .
Don't they still end up being worse than a Sid?
Depends on if you think heavier, more expensive and flexier than a SID are good or bad things for XC racing really.
You forgot to mention proprietary front hub as an advantage as well.
