Sorted myself out with a neat Stans Flow wheelset so my trusty Hope ProII Rear/Superstar Switch Front on Mavic EN321 wheels are for sale. 135mm QR rear, 20mm front. and Schrader valves. Great wheelset, takes loads of abuse.
The wheelset is in a used condition, with cosmetic scratches to the rims, mainly on the rear. Both wheels could benefit from a true, but haven't got any worse over the past couple of years so you could probably leave them as they are. Bearings in the front hub are starting to feel a little gritty if you turn it by hand, but it still goes round fine. Rear hub feels fine, it had new pawls and springs a few hundred miles ago and I regreased the freehub this afternoon. Usual pitting on the alloy freehub. Probably should mention that there's only rim stickers on the none drive side of the wheel.
£120 £115 £105 posted, which I think is a fair price. I can include a half worn 2.35 ST High Roller and ST Larsen TT for another £20.
