All new for 2014! Now comes with built in spacers so you don't have to worry about losing one when you're changing wheels. Yellow Jackets V2 bearings are designed from the ground up to be the best bearing on the market at this price point period. Yellow Jackets are superior because of the use of high quality grade balls, and they come in a sexy black surface finish. The result is a bearing that is as fast as Buzz bearings but are quieter, smoother, and longer lasting. Feel the buzz.
