Brand new (still in their box, never installed) Prime Attaquer Disc Wheelset. Shimano-type freehub. Superlight 700c tubeless-ready disc wheelset, these wheels are £375 at Wiggle/Chain Reaction and even at the RRP are probably the lightest you'll find for anywhere near this price.

The manufacturer's specifications are 1445g weight (665g front, 780g rear) but I haven't weighed this pair myself - bear in mind that will be excluding rim tapes, axles etc, as usual for weight specs. They come with all the originally supplied accessories still sealed in their packaging - a full set of QR/thru axle converters, tubeless valves, QR skewers, spare spokes, nipples and cassette spacer.
