Condor do provide that free 6 week service but I didn't take it back, even though it's only 5km from work.
On mine, some spokes on the rear wheel were coming loose after 300 miles. I tightened them up myself in my own hamfisted way. After 4000km several pairs of spokes were quite loose so I took it in to my LBS (W.F.Holdsworth) to be rebuilt (same spokes, just slackened off and rebuilt). It's done 6000km since then and is still perfectly tight and true. The SON wheel built by Paul Smith at Bike+ has done 9000km and is still rock solid.
The original Condor front wheel was removed almost straight away and replaced with a SON. I was planning on putting it back on for LEL as I'll be using battery lights. I may have to stick it on the bike for commuting duties to give it a good couple of thousand km shakedown.
Both were Open Pros on large flanged System-Ex hubs.
Maybe I was just unlucky with that particular wheel build but it's certainly tainted my view of Condor's wheel builds.
