Rota slipstreams are a knock off of the Spoon SW388. The Spoon wheel weighs just over 8 lbs, not sure how much the Rota weighs but It's probably twice that. Also, Rota wheels are not forged, there cast. Now that I know what I'm looking for I've found lots of cases of Rota wheels and other knockoffs breaking. How did Rota's get so popular with people who race if there a cheap heavy knock-off? Has anyone on here ever had a Rota wheel crack or break on them?
