They’re actually £599 for 2013, up from £499, and with no image available, I’d be very suspicious. Despite the £100 price hike I still think they’re great value for what they are though.
I believe the 2013 and 2012 wheels are identical aside from graphics. But I think 2012 saw a new rim design so I’d buy 2011 wheels with caution as well.
I’ve ridden 2012 26ers and 2013 29ers and they’re frankly superb wheels; very, very superb.
The 28mm rim width eclipses a lot of other so called All Mountain wheels, the 1760g weight eclipses a lot of so called xc wheels, yet I’ve had them down the FOD downhill trails and they’ve been nothing short of impressive. The real deal IMO.
