Fast forward a couple thousand years, give or take, and those brainy folks at the YoYo Factory combined a silicone pad response with high-quality SPEC bearing for 21st Century performance. Plus, Velocity has adjust-o-matic dials on each side that transform this bad boy from an old-school yo-yo into a modern-day bind-return yo-yo at the turn of a dial. If you’re just starting out, the old-school mode makes it easy to learn. And if you’ve already mastered the basics, then crank the dials all the way up to perform the most difficult tricks. Colors will vary.]]> Thu, 23 May 2013 21:55:16 +0000 http://www.marblesthebrainstore.com/grind-machine Yo-yos have been building muscle memory and whipping brains into shape for thousands of years. That’s all fine and dandy, but if you’re going to train your brain, you wanna look good while doing it. Say hello to the Grind Machine. This little beauty combines a modern shape and cool colors with high-performance features like a textured grinding surface, silicone response, large Central Bearing Co. SPEC bearing and patented triple bearing hubstack technology. So get ready to look sharp while doing the side-bind, finger grind, lanet hop, gyro flop and other yet-to-be-invented tricks. Yo-yo colors will vary.]]> Thu, 23 May 2013 21:55:16 +0000
