I've had my SL's for 2 years now, 3,000 miles no problems, STRONG, light, fast, smooth, comfortable, great looking too, on my sub 22 lb Epic EVO, I just over 200 lbs, I put in the plugs, they work great too. Never did anything but ride them, well worth the money, CycleTheropy in Waterford, Mi stocks these wheels, go get some, you'll never regret it, my only problem is I can't stop riding the bike now..
