Who needs a wheel upgrade or a spare set for 'cross season? I'm selling my 1 1/2 year old White Industries CLD wheelset with Pacenti SL25 disc rims and Sapim laser spokes.
The White Industries hubs are smoooth and a lovely mirror silver polished finish. US-made centerlock disc with a titanium Shimano/SRAM freehub body. 135mm QR rear, 100x15mm thru axle front (lots of end caps are available from White). Clicky but not too clicky.
The rims are Pacenti's "Goldilocks" SL25s: 700c, black, 26mm deep, and 24.5/20mm wide to give your tires a bit more width.
Wheels have been great on the road and for light graventure and are in good used shape. $450 OBO
