Beware!! I bought these wheels in August 2017 from a chinese ebay store, they looked good at first. I rode about 2500-3000 km until November 26th. The front wheel imploded at just 21 kph on a bike path. I hit a small 2 inch rock at 21 kph and the front wheel folded, I fell and bruised my ribs. Seller stated that the warranty didn't apply and offered another wheel and a reduced price. I was riding/talking with two friends and they couldn't beleive that a wheel will fold like that. I have had a wheelset from Bladex, also chinese, for 4 years and they still ride very good. No problems. Beware people.
