The all new Screaming Eagle line of Duncan high performance metal yo-yos are here and it's a whole new generation for Duncan. Duncan put together all the great minds of their crew to create this new series of great affordable metal yo-yos. Don't be fooled, this is not a Duncan metal yo-yo of the past, these bad boys play like a professional grade yo-yo is supposed to. It's sporting a D size bearing with silicone stickers and Duncan's new spinning side caps. The Momentum is an extremely smooth third edition to the Screaming Eagle line.
