These came stock on my Scatterini. I think they still come stock on a lot of different "sporty" road bikes. I was initially very unhappy when they developed a mystery tick after very few miles / hours. I ordered a set of Cane Creek Volos XL's on close out from Nashbar (luv 'em) and of course upon arrival of the new wheels the mystery tick vanished!!! Actually, I think it was something with the freehub, it made a horrible screech climbing one day and wala.. no more ticky. I moved them to my "rain bike" as part of my crafty upgrade scheme.. don't tell my wife.
As background.. I started out on these wheels around 240/245 and am now 205/210.
In any case, writing this to share what I think of the wheels after something near two years mostly on my rain/steel bike. They are low spoke count (20F/24R), but are heavy (1,938g)!! What moved me to write this was hitting a nice pothole today and coming out of it without issue. I think I put maybe a quarter turn on one or two spokes after the first couple rides, but have not touched them since and they are still very true and round. The flipside of these rims is the weight, compared to my other wheels (Cane Creeks) the acceleration feels noticably sluggish. I also think they look pretty good (bladed black spokes and fairly deep rim).
I know Alex rims can absolutely suck, a set of Alex 500's that came on my wifes bike were junk from the start and now serve only as trainer rims.. never been true, and remain wobbly even after 2 trips back to the LBS!! I gave up and bought her some mavic cxp/shimano wheels from Bicycle Wheel Wharehouse.. I think the "AClass" level Alex rims are a little better. They do say they are hand built, but for all I know that means some guy pushed a button to start the machine one day.
Overall grade: B- (would be and B, but I really hated them when they were ticking!!)
